1 September 1938: Jackie Cochran departed the Union Air Terminal, Burbank, California, at 3:00 a.m., flying her Seversky AP-7, NX1384, c/n 145. Her destination was Cleveland, Ohio, the finish line for the Bendix Trophy Race, 2,042 miles (3,286 kilometers) away.
NX1384 was built by the Seversky Aircraft Corporation of Farmingdale, Long Island, New York, especially for Jackie Cochran. It had been flown from the factory to Burbank by Major Alexander Nikolaievich Prokofiev de Seversky just two days earlier. His flight set an East-to-West Transcontinental Speed Record of 10 hours, 2 minutes, 55.7 seconds.
The AP-7 racer was an improved version of Major de Seversky’s P-35A fighter, which was the U.S. Army Air Corps’ first all-metal single-engine airplane with an enclosed cockpit and retractable landing gear.
Cochran’s AP-7 was powered by an air-cooled, supercharged, 1,829.39-cubic-inch-displacement (29.978 liter) Pratt & Whitney Twin Wasp S1B3-G (R-1830-11) two-row 14-cylinder radial engine rated at 850 horsepower at 2,450 r.p.m. at 5,000 feet (1,524 meters), and 1,000 horsepower at 2,600 r.p.m. for take off. The engine turned a three-bladed Hamilton-Standard controllable-pitch propeller through a 3:2 gear reduction. The R-1830-11 was 4 feet, 8.66 inches (1.439 meters) long with a diameter of 4 feet, 0.00 inches (1.219 meters), and weighed 1,320 pounds (599 kilograms).
“Finally the P-35 arrived. I decided that I didn’t want to take it into the air for a test even if I could. The racing officials impounded it because it was a prototype and there was some kind of rule about untested planes. I would test it en route. . . Finally, I got to sit in the cockpit. I began to study all the instruments by the hour. I can almost see them still.
“There are about a hundred or more buttons, levers, and other gadgets to push, pull or twirl. . . I close my eyes and reach for everything in the dark. And I keep at this until I can get to them blindfolded and with no false moves. . .
“I finally see Cleveland. . . (a)nd am going so fast that I pass the airport and come in from the wrong side. . . Have I won? The crowds are cheering. It’s a standing ovation. . . I have won the Bendix.”

“I often wonder what is meant exactly by a considered risk. . . In my case I never could ponder over the risks too much because I had to take a fast plane whenever it became available to me and make the best of it. I won the 1938 Bendix Race in a Seversky pursuit plane which I had never flown until that night, when, with a heavy overload of gas, I took off in the race. The plane was delivered from the factory to me just two days before the race and under the rules it had to be immediately impounded. It was a prototype that had not yest been tested. I tested it en route during the race. Its feature was that it had wings that were in effect integrated tanks so that most of the wings could be filled with fuel, thus adding range. It developed in flight that the fuel from the right wing would not properly feed the engine. By force on the stick I had to hold that wing much higher than the other from time to time in order to drain the fuel from that right wing into the left wing and from the left wing into the engine. When I got the plane back to the factory after the race a large wad of wrapping paper was discovered near the outlet of the right-wing tank. No wonder the drainage had been bad. How, for example, could that risk be properly considered i advance? The paper in the tank could have been sabotage. Some thought so at the time. More likely it was paper pasted on the inside of the wing during manufacture which had not been removed and which worked loose from the action of the gasoline and the vibration of the plane.”

Jackie Cochran was the third pilot to leave Burbank, but the first to arrive at Cleveland. Her elapsed time for the flight from California to Ohio was 8 hours, 10 minutes, 31.4 seconds, for an average speed of 249.774 miles per hour (401.895 kilometers per hour). For her first place finish, Ms. Cochran won a prize of $12,500.
After being congratulated on her win by Vincent Bendix and other race officials, Cochran had her Seversky monoplane refueled. She then got back in to its cockpit and took off for Floyd Bennett Field, new York. She landed there 10 hours, 12 minutes, 55 seconds after leaving Burbank. This was a new West-to East Transcontinental Speed Record.
