The President of the United States of America takes pleasure in presenting a Third Gold Star in lieu of a Fourth Award of the Distinguished Flying Cross to Major Edward N. LeFaivre (MCSN: 0-30579), United States Marine Corps, for heroism and extraordinary achievement while participating in aerial flight as Pilot of an F-4D-1 All Weather Fighter at the Naval Air Missile Test Center, Point Mugu, California, on 22 and 23 May 1958. Facing the dangers of a spin from near-vertical climbs in successive flights from a standing start, Major LeFaivre excelled four existing world records by climbing to 3,000 meters (9,842.5 feet) in 44.39 seconds; to 6,000 meters (19,685 feet) in one minute 6.13 seconds to 9,000 meters (29,527.5 feet) in one minute 29.81 seconds and to 12,000 meters (39,370 feet) in one minute 51.23 seconds, thereby breaking the existing world records set by France in February 1957. A climb to 15,000 meters (49,212.5 feet) in two minutes 36.05 seconds established the first official climb record to this height. In addition, the combined effect of engine flame-out, low airspeed and near-vertical altitude during the completion of the climb to 15,000 meters made a spin probable without sufficient control for recovery. Through his superb airmanship, initiative, and determination in the face of hazardous flight conditions, Major LeFaivre successfully demonstrated the maximum capabilities of the F-4D-1, and focused public attention on the contributions to the aeronautical developments made by the Navy and Marine Corps in advancing military aviation and national security. His outstanding professional skill and inspiring devotion to duty were in keeping with the highest traditions of the United States Naval Service.
