In October 1997, a Joint U.S.-Lao People's Democratic Republic team received information about a possible crash site. In late 2017, recovery teams found possible human remains and personal items. Further testing identified the three men:
—Pilot George L. Ritter, 49, of Philadelphia.
—Co-pilot Roy F. Townley, 52, of Ontario, California.
—Edward J. Weissenback, 29, of Richmond Hill, Queens, New York.
The three were on an Air America flight for the U.S. Agency for International Development, flying from Thailand to Xaignabouli Province, Laos. It went down on Dec. 27, 1971, near Syaboury, Laos. A search for the crew was unsuccessful.
