I was doing some reading on MH370 when I came across a mention of this story as related material.
It's very shocking and sad that these folks managed to survive an onboard fire, ditching, and even had the good Fortune of being located and observed after boarding lifeboats with ample survival gear and radios, only to completely disappear anyway.
Think this is as much a maritime mystery as it is a flight mystery. What possible tragedy could happen in mere hours that could completely wipe away all of those people, lifeboats, life jackets, and all? Even a rogue wave would have left the equipment scattered, but not sunk.
The whole thing just seems really unfair (as things are sometimes). Surviving everything they had should have meant they got to go home, but the Atlantic Ocean disagreed.
In 1951, I can't imagine any valid human threat that would have been patrolling the ocean. The Axis was finished. Russia was out there, but I have a hard time imagining them being motivated enough to ghost a stranded American crew.
Not going to get into wackadoo conspiracy theories. Bless them, wherever they went. en.m.wikipedia.org/ wiki/ 1951_Atlantic_C-124_disappearance
