August 9, 1945 Nagasaki

The 10,000lb, 10’8″ weapon was released at 28,900′. Seconds later, a perfect circle of 64 detonators exploded inside the heart of the bomb, compacting the plutonium core into a supercritical mass and  exploding with the force of 20,000 tons of high explosive.

The line comes from the Bhagavad Gita, the Hindu epic which Mohandas Gandhi described as his “spiritual dictionary”. On July 16, 1945, these words were spoken by J. Robert Oppenheimer, director of the Manhattan Project, as he witnessed “Trinity”, the world’s first nuclear detonation.

The project had begun with a letter from prominent physicists Leo Szilard and Albert Einstein to President Franklin Roosevelt, warning that Nazi Germany may have been working to develop a secret “Super Weapon”.  The project ended with the explosion of the “Gadget” in the Jornada del Muerto desert, equaling the explosive force of 20 kilotons of TNT.Trinity_site_plaque

The Manhattan Project, the program to develop the Atomic Bomb, was so secret that even Vice President Harry Truman was unaware of its existence.

President Roosevelt passed away on April 14, and Harry Truman was immediately sworn in as President. He was fully briefed on the Manhattan project 10 days later, writing in his diary that night that the US was perfecting an explosive “great enough to destroy the whole world”.

Nazi Germany surrendered on May 7, but the war in the Pacific theater, ground on. By August, Truman faced the most difficult decision ever faced by an American President. Whether to drop an atomic bomb on Imperial Japan.

The morality of President Truman’s decision has been argued ever since. In the end, it was decided that to drop the bomb would end the war faster, with less loss of life on both sides, compared with the invasion of the Japanese home islands.

So it was that the second nuclear detonation in history took place on August 6 over the city of Hiroshima, Japan. “Little Boy”, as the bomb was called, was delivered by the B29 Superfortress “Enola Gay”, named after the mother of United States Army Air Forces pilot Lieutenant Colonel Paul Tibbets. 70,000 Japanese citizens were vaporized in an instant.  Another 100,000 later died from injuries and the delayed effects of radiation.

Even then the Japanese Government refused to surrender. ‘Fat Man’, a plutonium bomb carried by the B29 “Bockscar”, was dropped on Nagasaki, on August 9.

The three cities originally considered for this second strike included Kokura, Kyoto and Niigata. Kyoto was withdrawn from consideration due to its religious significance. Niigata was taken out of consideration due to the distance involved.

Kokura was the primary target on this day, but local weather reduced visibility.  Bockscar criss-crossed the city for the next 50 minutes, but the bombardier was unable to see well enough to make the drop.  Japanese anti-aircraft fire became more intense with every run, and Second Lieutenant Jacob Beser reported activity on the Japanese fighter direction radio bands.

In the end, 393rd Bombardment Squadron Commander Major Charles Sweeney bypassed the city and chose the secondary target, the major shipbuilding center and military port city of Nagasaki.

The 10,000lb, 10’8″ weapon was released at 28,900′.  43 seconds later at an altitude of 1,650′, a perfect circle of 64 detonators exploded inside the heart of the bomb, compacting the plutonium core into a supercritical mass which exploded with the force of 20,000 tons of high explosive.

In the early 1960s, the Nagasaki Prefectural Office put the death count resulting from this day, at 87,000.  70% of the city’s industrial zone was destroyed.

Japan surrendered unconditionally on the 14th of August, ending the most destructive war in history.

Nazi Germany was, in fact, working on a nuclear weapon, and had begun before the allies. They chose to pursue nuclear fusion, colliding atomic particles together to form a new type of nuclear material, instead of fission, the splitting of the atom which resulted in the atomic bomb.

That one critical decision, probably taken in some laboratory or conference room, put Nazi Germany behind in the nuclear arms race. How different would the world be today, had Little Boy and Fat Man had swastikas painted on their sides.

May 23 1928  Crash of the Airship Italia

The airship’s control cabin hit the jagged ice seconds later, smashing open and spilling ten crew members and a Fox Terrier onto the ice.

The semi-rigid airship Italia departed from Milan on April 15, 1928, headed for the Arctic.  Italia carried 20 personnel, a payload of 17,000 pounds of fuel and supplies, and the expedition mascot, a Fox Terrier named Titina.

Stolp, Landung des Nordpol-Luftschiffes "Italia"

Her mission was to explore the ice cap surrounding the North Pole, operating out of an expedition base in Ny-Ålesund, one of four permanent settlements on Spitsbergen Island in the Kingdom of Norway.

italia mapThe first of five planned sorties began on May 11, before turning back only eight hours later in near blizzard conditions.  The second trip took place in near perfect weather conditions and unlimited visibility, the craft covering 4,000 km (2,500 miles) and setting the stage for the third and final trip departing on May 23.

Strong tailwinds aided the passage as Italia traveled north along the Greenland coast, arriving at the north pole only 19 hours after departing Spitzbergen. Though wind conditions prevented them from dropping scientists onto the ice sheet, survival packs and the inflatable raft they brought along for the purpose would turn out to be providential.

Trouble started almost immediately, as the tailwinds that brought them to the pole were now strong headwinds as they headed south to King’s Bay. Fuel consumption was doubled as the airship struggled to make headway.  After 24 hours, they were only halfway back.

A cascade of events took place on the morning of the 25th, causing Italia to be tail-heavy and falling at a rate of two feet per second. Captain Umberto Nobile ordered Chief technician Natale Cecion to dump ballast chain, but the steep deck angle made the task difficult. The airship’s control cabin hit the jagged ice seconds later, smashing open and spilling ten crew members and a Fox Terrier onto the ice.

Now relieved of the weight of the gondola, the envelope of the ship began to rise again with a gaping tear where the control cabin used to be.

What followed was a remarkable display of calm under pressure. As the airship’s italia-crashenvelope floated away, Chief Engineer Ettore Arduino started to throw everything he could get his hands on down to the men on the ice. These were the supplies intended for the descent to the pole, but they were now the only thing that stood between life and death. Arduino himself and the rest of the crew drifted away with the now helpless airship.

Nine survivors and one fatality were left stranded on the ice.  They immediately began to go through their supplies. They found a radio and fashioned a mast from the debris, and set up a tent after coloring it red using the dye contained in several flares.

The tale of the Italia rescue is a story in itself, as would-be rescuers themselves became stranded or disappeared into the arctic circle, never to be seen again.

The famous polar explorer Raould Amundsen, the man who first reached the pole in 1926, disappeared on June 18 while flying on a rescue mission with Norwegian pilot Leif Dietrichson, French pilot René Guilbaud, and a three-man French crew.

Rescue expeditions were launched from Denmark, Finland, France, Italy, Norway, Soviet Russia, Sweden, and the United States. Bureaucratic intransigence, equipment failure and a lack of coordination would hamper rescue efforts.  It would be more than 49 days before the last of the crash survivors and stranded would-be rescuers would be found. The fate of the journalist, the three mechanics and the scientist who drifted away on the Airship Italia, is unknown.

May 13, 1916 Lafayette Escadrille

The Lafayette Escadrille is often confused with the much larger Lafayette Flying Corps, and the movie “Flyboys” adds to the confusion.

Sous-Lieutenant_Norman_Prince_summer1916
Norman Prince

Knowing that his father would not approve, Norman Prince of Beverly Massachusetts concealed his flight training.  Using the name George Manor,  Norman earned his wings in 1911 in the Quincy, Massachusetts neighborhood of Squantum.  A fluent French speaker with a family estate in Pau, France, Norman sailed in January 1915, to join the French war effort.

The earliest vestiges of the American Hospital of Paris and what would become the American Ambulance Field Service can be found five years earlier, in 1906. Long before the American entry in 1917, individual sympathies brought Americans into the war to fight for Britain and France. They traveled to Europe to fight in the war against the Axis Powers, joining the Foreign Legion, the Flying Corps or, like Ernest Hemingway, the Ambulance Service.

After 1915, American pilots volunteered for multiple “Escadrille” – flight squadrons of the French Air Service, the Aéronautique Militaire.

The March 7, 1918 Harvard Alumni Bulletin, would give Norman Prince full credit for persuading the French government to form all-American flying squadrons, though he would not live to see the article.

Sergeant Norman Prince caught a landing wheel on a telegraph wire after a bombing run on October 12, 1916, sustaining massive injuries when his plane flipped over and crashed.  He was promoted to sous (2nd) lieutenant on his death bed and awarded the Legion of Honor.  He died three days later, at the age of 29.

William Thaw II of Pittsburgh was the first pilot to fly up New York’s East River under all four bridges, the first American engaged in aerial combat in the war.

Thaw pooled his money with three other pilots to purchase a male lion cub, the first of two such mascots kept by the Escadrille.  He bought the lion from a Brazilian dentist for 500 francs and bought a dog ticket, walking the lion onto the train on a leash.  Explanations that this was an “African dog” were less than persuasive, and the pair was thrown off the train.  “Whiskey” would have to ride to his new home in a cage, stuck in cargo.

Captain_Georges_Thenault_and_Fram_1917
French Lieutenant Colonel Georges Thenault & Fram, 1917

French Lieutenant Colonel Georges Thenault owned a “splendid police dog” named Fram who was the best of friends with Whiskey, though he learned to keep to himself at dinner time.

A female lion, “Soda”, was purchased sometime later.  The lions were destined to spend their adult years in a Paris zoo, but both remembered from whence they had come.  Both animals recognized William Thaw on a later visit to the zoo, rolling onto their backs in expectation of a good belly rub.

Originally authorized on March 21, 1916 as the Escadrille Américaine (Escadrille N.124), American pilots wore French uniforms and flew French aircraft.  Nevertheless, Germany was dismayed at the existence of such a unit, and complained that the neutral United States appeared to be aligning with France.

Lafayette EscadrilleEscadrille N.124 changed its name in December 1916, adopting that of a French hero of the American Revolution.  Marie-Joseph Paul Yves Roch Gilbert du Motier, Marquis de Lafayette. Five French officers commanded a core group of 38 American volunteers, supported by all-French mechanics and ground crew.  Rounding out the Escadrille were the unit mascots, the African lions Whiskey and Soda.

This early in aviation history, flying duty was hazardous to say the least.  Planes were flimsy and plagued with mechanical difficulties. Machine guns jammed and other parts failed when they were needed most.  There were countless wounds in addition to fatal injuries. At least one man actually asked to be sent back to the trenches, where he felt safer.

The first major action of the Escadrille Américaine took place at the Battle of Verdun on May 13, 1916. Kiffin Rockwell of Newport Tennessee became the first American to shoot down an enemy aircraft on May 18, later losing his own life when he was shot down by the gunner in a German Albatross observation plane on September 23. French born American citizen Raoul Lufbery became the squadron’s first Ace with 5 confirmed kills, and went on to be the highest scoring flying ace in the unit with 17 confirmed victories. He was killed on May 19, 1918, when his Nieuport 28 flipped over while he attempted to clear a jam in his machine gun.

The unit sustained its first fatality on June 24, 1916, when Victor Chapman was attacked by German flying ace Leutnant Kurt Wintgens, north of Douaumont.  Chapman was carrying oranges at the time, intended for his buddy Clyde Balsley, who was in hospital recuperating from an earlier incident.

Edmond Genet

Ossining, New York native Edmond Genet was a bit of a celebrity among American expats, as the second-great grandson of Edmond-Charles Genêt, of the Founding-era Citizen Genêt Affair.  Genet sailed for France at the end of January 1915, joining the French Foreign Legion, and finally the Lafayette Escadrille on January 22, 1917.

Genet had left while on leave from the US Navy, and was therefore classified as a deserter. The decision weighed heavily on him.  Edmond Genet was shot down and killed by anti-aircraft artillery on April 17, eleven days after the American declaration of war, officially making him the first American fatality in the War to end all Wars.  The war department sent his family a letter after his death, stating that his service was considered in all respects, honorable.

38 American pilots passed through the Lafayette Escadrille, “the Valiant 38”, eleven of whom were either killed in action or died later as the result of wounds received.  The unit flew for the French Air Service until the US’ entry into the war, when it passed into the 103rd Aero Squadron, American Expeditionary Force.

The Lafayette Escadrille is often confused with the much larger Lafayette Flying Corps, and the movie “Flyboys” adds to the confusion.  The Flying Corps was different from the Escadrille, the former coming about as the result of widespread interest in the exploits of the latter.  American volunteers were assigned individually or in groups of two or three to fly in various French Aviation units, but, prior to US entry into the war.  The Lafayette Escadrille was the only one to serve as a single organization.

All told, 267 American volunteers applied to serve in the Lafayette Flying Corps, credited with downing 199 German planes at the cost of 19 wounded, 15 captured, 11 dead of illness or accident, and 51 killed in action.

May 6, 1937 Hindenburg

The famous film shows ground crew running for their lives, and then turning and running back to the flames. It’s natural enough to have run, but there’s something the film doesn’t show.

Hindenburg left Frankfurt airfield on its last flight at 7:16pm, May 3, 1937, carrying 97 passengers and crew. Crossing over Cologne, Beachy Head and Newfoundland, the airship arrived over Boston at noon on the 6th.  By 3:00pm it was over the skyscrapers of Manhattan, arriving at the Naval Air Station in Lakehurst, NJ at 4:15.

Foul weather had caused a half-day’s delay, but the landing was eventually cleared.  The final S turn approach executed at 7:21pm. The ship was at the mooring mast, 180′ from the ground with forward landing ropes deployed, when flames first erupted near the top tail fin.

Eyewitness accounts differ as to the origin of the fire.  The leading theory is that, with the metal frameworkHindenburg grounded through the landing line, the ship’s fabric covering became charged in the electrically charged atmosphere, sending a spark to the air frame and igniting a hydrogen leak.  Seven million cubic feet of hydrogen ignited almost simultaneously.  It was over in less than 40 seconds.

The largest dirigible ever built, an airship the size of Titanic, burst into flames as the hull collapsed and plummeted to the ground.  Passengers and crew jumped for their lives and scrambled to safety, along with ground crews who had moments earlier been positioned to receive the ship.

The famous film shows ground crew running for their lives, and then turning and running back to the flames. It’s natural enough to have run, but there’s something the film doesn’t show.  That was Chief Petty Officer Frederick “Bull” Tobin, the airship veteran in charge of the landing party, bellowing at his sailors above the roar of the flames.  “Navy men, Stand fast!  We’ve got to get those people out of there!” Tobin had survived the crash of the USS Shenandoah on September 4, 1923.  He wasn’t about to abandon his post, even if it cost him his life. Tobin’s Navy men obeyed.  That’s what you see when they turn and run back to the flames.

The Hindenburg disaster is sometimes compared with that of the Titanic, but there’s a common misconception that the former disaster was the more deadly of the two. In fact, 64% of the passengers and crew aboard the airship survived the fiery crash, despite having only seconds to react.   In contrast, officers on board the Titanic had 2½ hours to evacuate, yet most of the lifeboats were launched from level decks with empty seats. Only 32% of Titanic passengers and crew survived the sinking.  It’s estimated that an additional 500 lives could have been saved, had there been a more orderly, competent, evacuation of the ship.

As it was, 35 passengers and crew lost their lives on this day in 1937, and one civilian ground crew.  Without doubt the number would have been higher, if not for the actions of Bull Tobin and is Navy men.

Hindenberg CrashWhere a person was inside the airship, had a lot to do with their chances of survival.  Mr and Mrs Hermann Doehner and their three children (Irene, 16, Walter, 10, and Werner, 8) were in the dining room, watching the landing.  Mr. Doehner left before the fire broke out.  Mrs. Doehner and the two boys were able to jump out, but Irene went looking for her father.  Both died in the crash.

For all the film of the Hindenburg disaster, there is no footage showing the moment of ignition. Investigators theorized a loose cable creating a spark or static charge from the electrically charged atmosphere.  Some believed the wreck to be the result of sabotage, but that theory is largely debunked.

Four score years after the disaster, the reigning hypothesis begins with the static electricity theory, the fire fed and magnified by the incendiary iron oxide/aluminum impregnated cellulose “dope” with which the highly flammable hydrogen envelope was painted.

The 35 year era of the dirigible was filled with accidents before Hindenburg, but none had dampened public enthusiasm for lighter-than-air travel. The British R-101 accident killed 48, the crash of the USS Akron 73. The LZ-4, LZ-5, Deutschland, Deutschland II, Italia, Schwaben, R-38, R-101, Shenandoah, Macon, and there were others.  All had crashed, disappeared into the darkness, or over the ocean.  Hindenburg alone was caught on film, the fiery crash recorded for all to see.  The age of the dirigible, had come to an end.

April 22, 1918 – The Red Baron

By way of comparison, the highest scoring Allied ace of the Great War was Frenchman René Fonck, with 75 confirmed victories. The highest scoring fighter pilot from the British Empire was Canadian Billy Bishop, who was officially credited with 72. The Red Baron had 80.

Early in the “Great War”, Manfred Freiherr von Richtofen was a cavalry scout, serving with the 1st Regiment of Uhlans Kaiser Alexander III in the Verdun sector. Cavalry quickly became obsolete, as the war of movement ended and armies dug in. Leutnant Richtofen served as a messenger over the winter of 1914-15, but there was no glory in crawling through the mud of shell holes and trenches. He applied to the fledgling Air Corps, writing to his superiors that “I have not gone to war in order to collect cheese and eggs, but for another purpose.”

Following four months of training, Richtofen began his flying career as an observer, taking photographs of Russian troop positions on the eastern front.Manfred_von_Richthofen

After transferring to Belgium and becoming bombardier, Manfred’s first air-to-air kill occurred in late 1915, while acting as observer and rear gunner on a two seat reconnaissance plane. The French pusher bi-plane went down over unfriendly territory and couldn’t be confirmed, so the victory was never counted. Neither was his second kill, when Richtofen shot down a French Nieuport fighter from an Albatross C.III bomber. This one too went down over enemy territory, and couldn’t be confirmed.

Richtofen had his first official victory on September 17, 1916, after being transferred to a fighter squadron. Manfred ordered a silver cup to mark the occasion, engraved with the date and make of the aircraft he had shot down, a British F.E. 2B.  Richtofen would add many more silver cups to his collection, before he was through.

Manfred got his 5th kill to become an ace on October 16, 1916, and the coveted “Blue Max” medal for his 16th, the following January. He shot down 22 enemy planes in April alone, four of those in a single day. Richtofen was Germany’s leading living ace, fast becoming the most famous pilot of his day, as German propagandists spread the rumor that the Allies were going to award the Victoria Cross to the man who shot him down.

Ever aware of his own celebrity, von Richtofen took to painting the wings of his aircraft a brilliant shade of red, after the colors of his old Uhlan regiment. It was only later that he had the whole thing painted. Friend and foe alike knew him as “the Red Knight”, “the Red Devil”, “’Le Petit Rouge’” and the name that finally stuck, “the Red Baron”.Fokker Triplane

Like Ted Williams, who was said to be able to count the stitches on a fastball, Richtofen was blessed with exceptional eyesight. Gifted with lightning fast reflexes, he became the top ace of the war. In an age when it was exceptional to score even a few air combat victories, Richtofen accumulated sixty engraved silver cups before the metal became unavailable in war ravaged Germany. Even then he was far from done.

Despite the popular link between Richthofen and his Fokker Dr.I, he only scored his last 19 kills while flying his famous red triplane. Three quarters of his victories were won in different makes of the Albatross and Halberstadt D.II.

By way of comparison, the highest scoring Allied ace of the Great War was Frenchman René Fonck, with 75 confirmed victories. The highest scoring fighter pilot from the British Empire was Canadian Billy Bishop, who was officially credited with 72. The Red Baron had 80.

Richthofen sustained a serious head wound on July 6 1917, causing severe disorientation and temporary partial blindness. He returned to duty after October 23, but many believed his injury caused lasting damage, leading to his eventual death.

Red Baron, last flightRichthofen chased the rookie Canadian pilot Wilfred “Wop” May behind the lines on April 21, 1918, when he found himself under attack. With a squadron of Sopwith Camels firing from above and anti-aircraft gunners on the ground, he was shot once through the chest with a .303 round, managing to land in a beet field before dying several minutes later. He was still wearing his pajamas, under his flight suit.

The RAF credited Canadian Pilot Captain Roy Brown with shooting the Red Baron down, but the angle of the wound suggests that the bullet was fired from the ground. A 2003 PBS documentary demonstrated that Sergeant Cedric Popkin was the person most likely to have killed Richthofen, while a 2002 Discovery Channel documentary suggests that it was Gunner W. J. “Snowy” Evans, a Lewis machine gunner with the 53rd Battery, 14th Field Artillery Brigade, Royal Australian Artillery. It may never be known with absolute certainty, who killed the Red Baron.Red Baron Crash Site

British Third Squadron officers served as pallbearers and other ranks from the squadron acted as a guard of honor for the Red Baron’s funeral on April 22, 1918. Allied squadrons stationed nearby presented memorial wreaths, one of which was inscribed with the words, “To Our Gallant and Worthy Foe”.

April 11, 1970  Houston, We’ve had a Problem

For four days and nights, the three-man crew lived aboard the cramped, freezing Aquarius, a landing module intended to support a crew of 2 for only 1½ days

Apollo 13 liftoffJack Swigert was supposed to be the backup pilot for the Command Module, (CM), officially joining the Apollo 13 mission only 48 hours earlier, when prime crew member Ken Mattingly was exposed to German measles. Jim Lovell was the world’s most traveled astronaut, a veteran of two Gemini missions and Apollo 8. By launch day, April 11, 1970, Lovell had racked up 572 space flight hours. For Fred Haise, former backup crew member on Apollo 8 and 11, this would be his first spaceflight.

The seventh manned mission in the Apollo space program was intended to be the third moon landing, launching at 13:13 central standard time, from the Kennedy Space Center in Florida.

The Apollo spacecraft comprised two separate vessels, separated by an airtight hatch. The crew lived in the Command/Service module, called “Odyssey”.  The Landing Module (LM) “Aquarius”, would perform the actual moon landing.

Apollo 13 Schematic

56 hours into the mission and 5½ hours from the Moon’s sphere of gravitational influence, Apollo crew members had just finished a live TV broadcast.  Haise was powering the LM down while Lovell stowed the TV camera.  Mission Control asked Swigert to activate stirring fans in the SM hydrogen and oxygen tank. Two minutes later, the astronauts heard a “loud bang”.

Spacecraft manufacturing and testing had both missed an exposed wire in an oxygen tank.  When Swigert flipped the switch for that routine procedure, a spark set the oxygen tank on fire. Alarm lights lit up all over Odyssey and in Mission Control.  The spacecraft shuddered as one oxygen tank tore itself apart and damaged another.  Power began to fluctuate.  Attitude control thrusters fired, and communications temporarily went dark. The crew could not have known it at the time, but the entire Sector 4 panel had just blown off.apollo-13-damage

The movie takes creative license with Commander James Lovell saying “Houston, we have a problem”.  On board the real Apollo 13 it was Jack Swigert who spoke, saying “Houston, we’ve had a problem”.

205,000 miles into deep space with life support systems shutting down, the Lunar Module became the only means of survival. There was no telling if the explosion had damaged Odyssey’s heat shields, but it didn’t matter. For now, the challenge was to remain, alive.  Haise and Lovell frantically worked to boot up Aquarius, while Swigert shut down systems aboard Odyssey, in order to preserve power for splashdown.

Apollo_13-insigniaThis situation had been suggested during an earlier training simulation, but had been considered unlikely. As it happened, the accident would have been fatal without access to the Lunar Module.

For four days and nights, the three-man crew lived aboard the cramped, freezing Aquarius, a landing module intended to support a crew of 2 for only 1½ days. Heat fell close to freezing and food became inedible, as mission control teams, spacecraft manufacturers and the crew itself worked around the clock to jury rig life support, navigational and propulsion systems.  This “lifeboat” would have to do what it was never intended to do.

Atmospheric re-entry alone, presented almost insurmountable challenges. The earth’s atmosphere is a dense fluid medium. If you reenter at too steep an angle, you may as well be jumping off a high bridge. As it is, the human frame can withstand deceleration forces no higher than 12 Gs, equivalent to 12 individuals identical to yourself, piled on top of you.  Even at that, you’re only going to survive a few minutes, at best.

Apollo_13_Prime_Crew
Left to right: Commander, James A. Lovell Jr., Command Module pilot, John L. Swigert Jr., Lunar Module pilot, Fred W. Haise Jr.

We all know what it is to skip a stone off the surface of a pond.  If you hit the atmosphere at too shallow an angle, the result is identical. There is no coming down a second time. You get one bounce and then nothing but the black void of space.

For four days, most of the country and much of the world held its breath, waiting for the latest update from newspaper and television news.  With communications down, TV commentators used models and illustrations, to describe the unfolding drama.  Onboard Odyssey, power was so low that voice-only transmissions became difficult. Visual communications with Mission Control were as impossible, as the idea that the stranded astronauts could walk home.

As Odyssey neared earth, engineers and crew jury-rigged a means of jettisoning the spent Service Module, to create enough separation for safe re-entry.Apollo_13_timeline

One last problem to be solved, was the crew’s final transfer from Lunar Module back to Command Module, prior to re-entry.  With the “reaction control system” dead, University of Toronto engineers had only slide rules and six hours, in which to devise a way to “blow” the LM, by pressurizing the tunnel connecting it with the CM.  Too much pressure might damage the hatch and its seal, too little wouldn’t provide enough separation between the two bodies.  The result of either failure, would have been identical to that of the “shooting stars”, you see at night.

Apollo 13 after it came back to Earth.
Apollo 13 after it came back to Earth.

By this time the Command Module had been in “cold soak” for days.  No one even knew for certain, if the thing would come back to life.

Crashing into the atmosphere at over 24,000mph, the capsule had 14 minutes in which to come to a full stop, splashing down in the waters of the Pacific Ocean. External temperatures on the CM reached 2,691° F, as the kinetic energy of re-entry was converted to heat.

The Apollo 13 mission ended safely with splashdown southeast of American Samoa on April 17, 1970, at 18:07:41 local time.  Exhausted and hungry, the entire crew had lost weight.  Haise had developed a kidney infection.  Total duration was 142 hours, 54 minutes and 41 seconds.

February 28, 1944 Test Pilot

The Arado Ar 96 left the improvised airstrip on the evening of April 28, under small arms fire from Soviet troops.  It was the last plane to leave Berlin.  Two days later, Hitler was dead.

Hannah Reitsch earned her wings in the 1930s, as a flying missionary.  The Encyclopedia Britannica describes her as the first female test pilot in Germany.  If she wasn’t the first female test pilot in history, I’d be interested to know who that might be.
Reitsch began flying gliders in 1932, as the treaty of Versailles prohibited anyone flying “war planes” in Germany. In 1934, she broke the world’s altitude record for women (9,184 feet).  Hannah Reitsch was a German Nationalist, and her work brought her into contact with the highest levels of Nazi party officialdom.
hannah-reitschAs a test pilot, Reitsch won an Iron Cross, Second Class, for risking her life trying to cut British barrage-balloon cables. On one test flight of the rocket powered Messerschmitt 163 Komet in 1942, she flew the thing at speeds of 500 mph, a speed nearly unheard of at the time. She spun out of control and crash-landed on her 5th flight, leaving her with severe injuries.  Her nose was all but torn off, her skull fractured in four places.  Two facial bones were broken, and her upper and lower jaws out of alignment.  Even then, she managed to write down what had happened before passing out.
Reichsmarshall Hermann Göring awarded her a special diamond-encrusted version of thehitler_goering_und_hanna_reitsch Gold Medal for Military Flying on this day in 1944. Adolf Hitler personally awarded her an Iron Cross, First Class.
It was while receiving this second Iron Cross in Berchtesgaden, that she suggested the creation of a Luftwaffe suicide squad, “Operation Self Sacrifice”.
Hitler was initially put off by the idea, though she finally persuaded him to look into modifying a Messerschmitt Me-328B fighter for the purpose. Reitsch put together a suicide group, becoming the first to take the pledge, though the idea would never take shape. The pledge read, in part: “I hereby voluntarily apply to be enrolled in the suicide group as a pilot of a human glider-bomb. I fully understand that employment in this capacity will entail my own death.”
The plan came to an abrupt halt when an Allied bombing raid wiped out the factory in which the prototype Me-328s were being built.
In the last days of the war, Hitler dismissed his designated successor Hermann Göring, over a telegram in which the Luftwaffe head requested permission to take control of the crumbling third Reich.  Hitler appointed Generaloberst Robert Ritter von Greim, ordering Hannah to take him out of Berlin and giving each a vial of cyanide, to be used in the event of capture.   The Arado Ar 96 left the improvised airstrip on the evening of April 28, under small arms fire from Soviet troops.  It was the last plane to leave Berlin.  Two days later, Hitler was dead.berlin-wwii
Taken into American custody on May 9, Reitsch and von Greim repeated the same statement to American interrogators: “It was the blackest day when we could not die at our Führer’s side.” She spent 15 months in prison, giving detailed testimony as to the “complete disintegration’ of Hitler’s personality, during the last months of his life.  She was found not guilty of war crimes, and released in 1946. Von Greim committed suicide, in prison.
In her 1951 memoir “Fliegen – Mein Leben”, (Flying is my life), Reitsch offers no moral judgement on Hitler or the Third Reich.
She resumed flying competitions in 1954, opening a gliding school in Ghana in 1962.  She later traveled to the United States, where she met Igor Sikorsky and Neil Armstrong, and even John F. Kennedy.Hanna Reitsch, Fliegen Mein Leben
Reitsch remained a controversial figure, due to her ties with the Third Reich.  Shortly before her death in 1979, she responded to a description someone had written of her, as `Hitler’s girlfriend’.  “I had been picked for this mission” she wrote, “because I was a pilot…I can only assume that the inventor of these accounts did not realize what the consequences would be for my life.  Ever since then I have been accused of many things in connection with the Third Reich”.
Toward the end of her life, she was interviewed by the Jewish-American photo-journalist, Ron Laytner. Even then she was defiant:  “And what have we now in Germany? A land of bankers and car-makers. Even our great army has gone soft. Soldiers wear beards and question orders. I am not ashamed to say I believed in National Socialism. I still wear the Iron Cross with diamonds Hitler gave me. But today in all Germany you can’t find a single person who voted Adolf Hitler into power … Many Germans feel guilty about the war. But they don’t explain the real guilt we share – that we lost”.
Hannah Reitsch died in Frankfurt on August 24, 1979, of an apparent heart attack.  Former British test pilot and Royal Navy officer Eric Brown received a letter from her earlier that month, in which she wrote, “It began in the bunker, there it shall end.”  There was no autopsy, or at least there is no report of one.  Brown, for one, believes that, after all those years, she had finally used that cyanide capsule.
