The Curtiss JN-4 Jenny, the Government Surplus Sale of 1919, and the Two-Hundred-Dollar Biplane That Sold America on Flying

The United States Army ended World War I with roughly 6,400 surplus Curtiss JN-4 “Jenny” biplanes and no use for them. The government sold them off for as little as $200, and the veterans who bought them spent the next eight years barnstorming across the American heartland - introducing nearly a million people to flight and building the audience that would eventually fill the airlines.

What Was the Curtiss JN-4 Jenny?

The JN-4 was the backbone of American military pilot training from 1916 through the end of World War I. Virtually every American military aviator - and many Canadians - learned to fly in one. It was a wood, wire, and fabric biplane, flown open cockpit, powered by the Curtiss OX-5: a 90-horsepower water-cooled V-8 that ran on castor oil and was known for both its versatility and its unreliability.

The Jenny had a landing speed of around 45 miles per hour and a service ceiling of roughly 6,500 feet. Its two-seat tandem configuration put the passenger up front. For pilots looking to charge the public for rides, it was purpose-built - even if that purpose was never intended by Curtiss or the Army.

The 1919 Government Surplus Sale

The Armistice on November 11, 1918 left the Army holding an inventory of aircraft it no longer needed. By 1919, returning veterans who could scrape together $200 to $300 could walk away with a surplus Jenny - some crated in cosmoline for as little as $50. For context, a new Model T Ford cost roughly $350 at the time. Entry into aviation was cheaper than entry into the automobile market.

There were no commercial airline routes, no passenger terminals, and no instrument approaches. There was no established use for a privately-owned airplane. That created a vacuum, and a generation of veterans with flying skills and little else filled it.

How Barnstorming Worked

The barnstorming model was borrowed directly from traveling theater companies of the 1800s, which rented barn space to perform before moving on to the next town. Aviation’s barnstormers applied the same logic: fly into a town, make enough noise on approach to draw attention, land in the nearest flat field, and charge one dollar per passenger for a ride.

The Jenny made this viable. Its 45 mph landing speed meant almost any reasonably flat field served as a runway. Its passenger seat was immediately available. Pilots fixed what broke with fence wire, hardware store parts, and optimism. The low acquisition cost meant that even a cracked wing was financially survivable.

The OX-5 Engine: Personality and Problems

The OX-5 had a reputation among pilots that went well beyond its technical specifications. It vapor-locked in hot weather. It seized without sufficient water. Oil delivery was monitored through a sight glass in the cockpit - a small window where the pilot watched oil drip at the correct rate. When that drip stopped, the engine was about to stop running.

Pilots had a saying: trust God, distrust the OX-5. Its service life was roughly 300 hours under careful maintenance - far less under field conditions. Yet it earned genuine loyalty. Long after the engine became obsolete, barnstorming veterans formed the OX-5 Aviation Pioneers, an organization that held reunions well into mid-century. There is something about a difficult machine that bonds the people who mastered it.

The Flying Circuses

By the early 1920s, individual barnstormers were pooling resources into flying circuses. The economics were straightforward: one pilot doing passenger hops was a novelty; four pilots, a wing walker, and a man jumping between aircraft in flight was an event people drove from three counties away to see.

The Gates Flying Circus, the Thirteen Black Cats, and the Flying Aces were among the most prominent. They worked county fairs and harvest festivals with the confidence of people selling something genuinely extraordinary - because they were.

Wing Walkers: Skill at Altitude

The wing walkers were not sideshow performers. They were skilled athletes executing technical feats at altitude, often without harnesses, with no safety net and no margin for error. Lillian Boyer became famous for car-to-plane transfers - catching a rope ladder dropped from a low-flying Jenny while standing on the running board of a moving automobile. Ethel Dare, billed as the Flying Witch, drew crowds in the tens of thousands.

Standing upright on the upper wing of a Jenny at 60 miles per hour and 1,000 feet was a discipline, not a stunt.

Famous Pilots Who Flew Jennies

Charles Lindbergh bought his first Jenny in 1923 and barnstormed through the Midwest before transitioning to the airmail routes. He later described those years as formative - the period when he understood that flying was a relationship between pilot and air, not just a mechanical skill.

Amelia Earhart took her first airplane ride in 1920 at Daugherty Field in Long Beach, California, in a Jenny flown by barnstormer Frank Hawks. She began taking flying lessons within six months.

Why the Barnstorming Era Ended

The Air Commerce Act of 1926 required the certification of both pilots and aircraft. For barnstormers flying unlicensed aircraft that would never pass inspection, the cost of compliance exceeded what the business could absorb. The era was also simply running out of airplane: wood and fabric don’t survive a decade of field landings and open-air storage, and no one was still manufacturing OX-5-powered trainers.

Lindbergh’s transatlantic crossing in May 1927 closed the chapter definitively. Aviation became serious, professional, and institutional. The barnstormers didn’t end with a catastrophic crash. They ended with quiet obsolescence - the sky had gotten serious, and it couldn’t hold them anymore.

Why the Barnstormers Matter to Aviation History

By some estimates, nearly one million Americans took their first airplane ride during the barnstorming era - roughly 1919 through 1927. These were farmers, schoolteachers, factory workers, and children who had never seen an aircraft up close. For a dollar, sometimes less, they climbed into the front seat of a Jenny and looked down at the world from 500 feet.

When the airlines began selling tickets in the late 1920s and early 1930s, they were selling to a public that had already been converted. The barnstormers built that audience one field landing at a time, years before the first scheduled route was ever published. They flew into fields nobody asked permission for, stood in front of people who had never seen this thing, and asked: do you want to come up?

And America said yes.

Key Takeaways

• The 1919 government surplus sale put roughly 6,400 Curtiss JN-4 Jennies on the civilian market for as little as $200 - less than the cost of a new Model T Ford.
• The Jenny’s 45 mph landing speed and two-seat tandem design made it nearly ideal for the barnstorming business model, turning any flat field into a makeshift airfield and revenue opportunity.
• Flying circuses like the Gates Flying Circus and the Thirteen Black Cats scaled barnstorming into organized spectacle, drawing crowds from across entire regions.
• Both Charles Lindbergh (1923) and Amelia Earhart (1920) had formative early experiences in JN-4 Jennies during the barnstorming era.
• The Air Commerce Act of 1926 and aging Jenny airframes effectively ended the era; Lindbergh’s 1927 Atlantic crossing redirected aviation’s ambitions toward commercial flight - an audience the barnstormers had spent eight years creating.
