EC-121R Constellation 67-21487, "Da Nang Glider", 553rd RS/553rd RW, USAF, Korat RTAFB, Thailand, June 1969 
 
General Background
As a response to the Douglas DC-4, Lockheed developed the Constellation. As more powerful engines were developed the Constellation was stretched 21 feet and improvements made resulting in the L-1049 Super Constellation. The development of the L-1049G improved range with the addition of wing-tip tanks. The more powerful engines made it necessary to use large propellers that required the aircraft to sit quite high off the ground. A triple tail was developed because the size of a single tail would have been too large to fit in any hangar.
