My God
nutty as it looks, at least in flight the F-84s would have been generating some lift, on the ground they're just an awful lot of dead weight right at the very extremities of the B-29's wings; the accident doesn't really come as a great surprise, what comes as a surprise is that it didn't fold up just trying to get off the ground - that stage of the ride must have been a real pucker-clench for the F-84 drivers...
Assuming worst case, if the bomber got all the way out to the target and the F-84s were required in defensive combat ie some rigorous fuel-burning, would the pair of them (assuming both survived) have the fuel to make it home? Or would there be some contingency airfield they could stage through?
