Chapter 3 The Golden Age
Preview Questions • What were some early goals/milestones in aviation? • How did the war ending affect the aviation industry? • What happened to military pilots and planes after the war? • Who were the barnstormers? • How did they help aviation?
Flying the Atlantic • 1st attempt made by Cmdr. Read (Navy) • May 16, 1919 • From Trepassey, Newfoundland to Lisbon Portugal • Arrived May 20, 1919 • Total time 26 hours 45 minutes • First transatlantic crossing • First nonstop only 2 weeks later • 16 hours 12 minutes, June 14th to 15th • Newfoundland to Ireland • Capt. Alcock and Lt. Brown
After the War • Airplane numbers at end of war • France 67,982 • Germany 47,637 • Italy 20,000 • America 15,000 • British production, during war, from 20/month to 3,500/month • At the end, 177,000 aircraft in service
3 days after war ends, US Government cancels $100 million in airplane contracts • 175,000 workers laid off • Industry production dropped 85% • Surplus airplanes sold to the public, cheap • Military aviation cut 95% • Closed most airbases • Now, lots of trained people with tons of time and lots of cheap cutting edge (for the era) equipment
Barnstormers • Mostly ex-military • Flying war surplus aircraft • Like the Curtiss JN-4 Jenny • Flew from town to town giving rides • About $5 a ride • May have joined a carnival or traveling fair • Sometimes groups of pilots would join together and form a “flying circus”
Wing-walkers • Pilot flew, they would get out and walk on wing • First licensed black female pilot • Bessie Coleman • Died in plane crash • Barnstormers brought aviation to the masses and created a greater interest • Helped keep aviation alive between wars
Military Air Power Develops • Gen. “Billy” Mitchell still campaigning for separate and equal “Air Force” branch • Believes that future of warfare lies with offensive aircraft • Wanted to upstage the Navy • Asked to be allowed to bomb ship to demonstrate superiority • Congress offers captured German ship • Thought to be unsinkable
The Bomb Run • First day, light bombs, little damage • Second day, 1000 pounders, still minimal damage • Day three, 2000 pounders, ship sinks in 30 min. • Lesson lost on everyone • Mitchells requests refused • This does convince the Navy of the future of the airplane, first aircraft carrier built early 1922
Flight Around the World • 1924, 4 Douglas airplanes left Seattle • The aircraft • Boston, down between England & Iceland • Chicago, made it • Seattle, crashed in Alaska • New Orleans, made it • Took 175 days, only 2 planes made it back
Route: • Seattle, Alaska, Japan, China, Indochina, Burma, India, Syria, Austria, France, England, Iceland, Greenland, Labrador, Newfoundland, Seattle
Further Accomplishments • 1923, first airborne refueling • Stayed aloft for 37 hours 15 min • 1924, first coast to coast flight within 24 hours • Took 21 hours 47 min • Demonstrated that anyone could be anywhere in the country within a day • 1929, first use of paratroops • 18 men, weapons and supplies jumped at 3000 feet
Discussion • Why were Americas airplane numbers so low at the end of the war? • What did the end of the war mean for aviation? • Examples? • What was the most important thing barnstormers did?

(companies) • What is high wing and low wing? • When you hear “Sikorsky” what comes to mind? • Which airplane became the standard for most airlines? • Pan Am cornered what market of aviation? • Most famous Zeppelin? • Tuskegee Airmen?
Growth • 1920s, growing market for private aircraft • Many small companies formed to meet demand • Travel Air Manufacturing Company • Wichita KS • Lloyd Stearman, Clyde Cessna, Walter Beech • Built biplanes • Cessna believed a monoplane would be more successful
The other 2 partners did not agree • 1927 Cessna left and started Cessna Aircraft Company • Later the last 2 partners started their own companies • Beech Aircraft Co., 1932 • Stearman Aircraft Co., 1933 • All 3 stayed in Wichita KS • Area referred to as the light aircraft capitol of the world

1915, Pres. Wilson formed NACA • National Advisory Committee for Aeronautics • “supervise and direct scientific study of the problems of flight, with a view of their practical solutions” • 1926, Daniel Guggenheim • NY philanthropist • Founded School of Aeronautics at NYU • Established $2.5 million “Daniel Guggenheim Fund for the Promotion of Aeronautics” • Supplied grants and scholarships to student across the country
