Boyd was killed on May 15, 1975, in a rescue attempt of the captured crew of the SS Mayaguez. The helicopter he was flying in came under heavy enemy fire as it approached the island where the crew was being held captive and crashed into the surf with 26 men on board. Half were rescued at sea, leaving 13 unaccounted for. Boyd was listed as Missing In Action until only recently. SHARE: Download: Full Size (0.06 MB) Credit: VIRIN: 245357-W-IFX00-587.jpg Photo Gallery
