Today in MilAvHist, 9/6/1944, the McDonnell XP-67 project came to a flaming end. While on a test flight, the sole flying XP-67's starboard engine caught fire and was brought into Lambert Field, St. Louis.
Upon landing the test pilot attempted to pivot and turn the aircraft into the wind to blow the flames away from the fuselage, but the brakes then failed. The aircraft pivoted the wrong way and flames engulfed the entire airplane with the pilot escaping unharmed.
The XP-67 was a prototype for a twin-engine, long-range, single-seat interceptor aircraft for the United States Army Air Forces. The aircraft was plagued with problems and it's 9 months of flying were spent trying to improve poor engine performance and overheating as well as aerodynamic issues. (Museum of the USAF photos).
