On 1/29/43, the pilot 2nd Lt. Scott B. Kidd was flying the P-39Q #44-3082 on a routine gun camera mission. He had climbed to the altitude of 9,500 feet when he noticed that the engine was running rough. Upon checking the instruments, he observed that the manifold pressure was dropping steadily and the oil pressure was down to zero. The pilot gave this information to ground control and they instructed him to abandon the aircraft, which he did immediately. The pilot was thrown clear of the aircraft, passed over the top of the tail, opened his parachute and descended without any injuries. It was the opinion of the Accident Investigation Board, that the loss of oil pressure during flight was caused by the failure of an oil line in the rear section of the engine, after the oil tank was recently replaced due to a leak in the old tank. The crash site is north of Las Vegas, Nevada.
