They don’t make volunteers like they used to. On August 17, 1946, First Sergeant Lawrence Lambert became the first person in the United States to be shot out of a speeding aircraft.
His shot (as in “out of a cannon”; at least that’s what it must have felt like) was the first U.S. manned test of an ejection seat. U.S. Air Force source documents note that Lambert’s P-61 was traveling more than 300 miles per hour, at an altitude of 6,000 feet. “Lambert was thrown approximately 40 feet in the air at a speed of nearly 40 miles an hour for that distance,” notes the report. “The ejector seat shoots a pilot straight up at a speed of approximately 60 feet per second. Though this is only about 40 miles per hour, the speed must be reach[ed] almost instantly, and this entails a rapid acceleration and thus a terrific strain. The acceleration increases a man’s weight momentarily. A 200-pound man might weigh nearly two tons at the acceleration used by the ejector.” Lambert experienced between 12 to 14 Gs as he ejected; he cleared the P-61′s tail fin by a mere 20 feet.
For this test, Lambert received the Distinguished Flying Cross. The recommendation for the citation, put forward by Colonel C.K. Moore, reads in part, “Sergeant Lambert’s courageous acceptance of this responsibility and successful demonstration of the highly experimental equipment has helped to solve one of the most acute problems faced by the Army Air Forces—the escape of personnel from the high speed aircraft in present operation and aircraft of higher speeds to come. His achievement has immeasurably advanced aerodynamic and medical knowledge and will make possible improved methods of escape heretofore unknown.”
