Now that I have had a bit if time to ponder, with the few details in this story, would it not tend to negate most of the TIGHAR and NUMA theories, that the White Bird ended up on land?
Still, two "white wings" found floating in the ocean three months later don't have too many other likely suspects. Even though the White Bird jettisoned its gear on takeoff and was theoretically supposed to be able to land on the water, and float for some time, I don't fancy trying to land a non-seaplane on anything other than a mirror-flat body of water and have it come out OK. The chances of catching a wingtip or doing a noseover are just that much greater than with a proper seaplane, especially if they had to attempt it at night or under reduced visibility. Still, it looks more and more like they did make it.
