The crew was engaged in a training sortie out from Carswell AFB. Just after liftoff, while in initial climb, the crew informed ground that he lost an engine cowling and obtained the permission to return for a safe landing. On touchdown, one of the main landing gear collapsed. The heavy bomber went out of control, veered off runway and came to rest in flames, killing seven crew members. It was reported that the total weight of the airplane upon landing was too high, causing the undercarriage to collapse.
