Red beret

During the search for a U.S. hydrogen bomb lost in the Mediterranean off Spain in 1966, the Human Occupied Vehicle Alvin operated from a Navy dock landing ship. The red beret was adopted as a badge of camaraderie by the Alvin group during its early years after pilot Val Wilson, originally hired as skipper for Lulu, came back from a trip to the Bahamas sporting one.(Photo courtesy of Woods Hole Oceanographic Institution Archives)
