Does it look possible that this P40 landed with its gear down?
Interesting point, but I would suggest yes. At the start of the second video it appears that the tailwheel is down and the tailwheel bay doors are in the 'gear down' position (unlikely they would have ended up there if the doors were closed on impact?). There are known cases of aircraft landing successfully in the open desert with gear down, so perhaps this aircraft did so too.
