Utahn among missing Vietnam War veterans honored by new monument By: FOX 13 News and last updated 2021-05-15 22:29:09-04 COLUMBIA FALLS, Maine â On Saturday, a group called Wreaths Across America honored soldiers whose disappearance remains one of the biggest mysteries of the Vietnam War. Flight 739, nicknamed "The Flying Tiger," went missing on March 16, 1962, and the 93 U.S. Army Rangers on board were presumed dead. No trace of wreckage was ever recovered, and due to the complexities surrounding the mission, the names of all those on board have not yet been added to the Vietnam Veterans Memorial in Washington, D.C.
