What a fantastic story! Its entirely possible though that nobody could get DNA from the recovered bones, reading through the story, no it's not possible to get DNA from dinosaur bones as the poor pilot's relative thought, there are no dinosaur bones, there are only dinosaur bone fossils, the bone itself with the DNA dissolved away long before they were fossilised and replaced by minerals leeching into the void. One of the worst things for destroying DNA is ultraviolet light (that's what causes melanomas in skin) and there's an awful lot of UV in the desert (but none six foot under a car park)
Its a real shame but from the wonderful condition of the P40 and the fact that the radio and batteries were removed from the plane I'd say there was a pretty good chance that the poor man survived the crash landing and that the bones are his remains.
Its even sadder that the descendants of those this man died to save from the nazis should regard a priceless piece of history as junk!
