Flying Tigers Line Flight 739, a Lockheed L-1049H, was chartered by the United States military. Originating at Travis Air Force Base, California, the Military Transport was scheduled for fueling stops at Honolulu, Wake Island, Guam, Clark AFB and was to terminate in Saigon.
According to the Civil Aeronautics Board’s (CAB) Accident Report, “The plane disappeared 1 1/2 hours after takeoff from Guam enroute to Saigon.” And “the largest air/sea search” of that time “was initiated 5 hours after the plane’s fuel exhaustion time.” “The S/S T.L. Lenzen, a supertanker owned by Standard Oil, was in the vacinity and witnessed a vapor trail go behind a cloud,” and then, (what they thought was according to the depositions of the crew) “a covert operation due to the low flying plane.” The Accident Report continues, that the crew of the S/S T.L. Lenzen had also witnessed “a mid-air explosion at the approximate time & location of N6921C.” The Accident Report concludes, “Due to the lack of any substantiating evidence the Board is unable to state with any degree of certainty the exact fate of N6921C.”
The Department of Defense has “excluded this flight,” from it’s own criteria, which would enable these 107 names being included on the Vietnam Veteran’s Memorial (The WALL) in Washington, D.C. | source
