Wonder what the depth is? Looks like that diver is loaded up with mixed gas.
B-17
My dad flew as a B24 tailgunner in those campaigns. Flying out of Spinazolla Italy on the boot.
These planes came from the attacks most likely from the raid on Ploesti Oil Fields, a force of 177 planes attacked and 54 lost outright with another 55 damaged and some of those ditched at sea on the trip back..Single worse loss up that point in the war.
Reason for using only the B-24 was had longer range than the B-17 and carried bigger load than the B-17. Flew like a truck without power steering. Ditching at sea or crash landing on land was extremely risky as the plane had a high wing and roll up bomb bay doors which acted as a brake and ripped the plane apart.
