I believe I read something about that a few years ago. I'm thinking they found his P-38 in a harbor.
Yes, there was some P-38 wreckage found in a harbor in the Mediterranean, just off the the city of Marseilles coast. The find is suggestive, but not definitive. There are no numbers on any part of the wreckage found to confirm that it is "St. Ex's" plane. BTW, he was the oldest fighter pilot of the war. He was 40 years old when he disappeared while flying un-armed, photo-recon, PR-38's across Europe from No. Africa and back. His writings have had a profound influence on my life. I put "St. Ex" right up there with T. Jefferson.
