YouTube has a video about Lt Earl Stone. Spike Nasmyth is the main speaker. Lt. Stone’s brother, (a WWII bomber pilot) and his niece, Elizabeth also speak. Spike was a fighter pilot in Viet Nam and POW of North Viet Nam for 7 years. He lives here in the Philippines. He organized the private recovery expeditions and I was able to help a couple of times.
