YT-14 (BuNo 154042) of HMM-164 was the last Marine helicopter lost in Vietnam (29 April 1975), and still sits at the bottom of the South China Sea in 65 - 100 feet of water at coordinates 09 55'32 N, 107 20'06 E, or at approximately 30 nautical miles on the 150 o radial of the Vung Tau NDB. We need your help to honor Captain Nystul and Lt. Shea and bring them home!
