They don't care if it's scrap or not- - - -as long as it's not somewhere in China being reverse engineered. The Russians did that with a crashed B-29 back in the 1940's. I hope the keel-hauled the pilot for that screwup, though!
Yes the fallback plan for B29s that were bombing Japan was, if they couldn't make it back to a US base, was for them to land in our ally, Russia. And more than one did. The Russians began building their new fleet of bombers, an exact copy of the B29.
