Obscure movie for the day

Rico says that would be Sole Survivor, an odd little World War Two ghost story starring William Shatner as a captain, but not Kirk:

When a bomber believed to have crashed in the ocean seventeen years ago is found in the Libyan desert, a colonel (played by William Shatner) and a major (played by Vince Edwards) accompany the only surviving member of the crew, now a general (played by Richard Basehart), to figure out what happened. The general claims that he and the other members of the crew jumped over the ocean when, in reality, he bailed out by himself, leaving the others to fend for themselves. While the colonel just wants the whole thing closed, the major insists on finding the truth. Watching them are the ghosts of the crew.

Rico says it's full of intrigue and flashbacks, and sometimes hard to follow, but well done...
