Hi Widewing,
>This unfortunate P-47 was the victim of a 500 pound bomb which fell from its fuselage shackle and exploded.
I don't believe a 500 lbs bomb going off right below any aircraft would have left the pilot with any chance of survival.
The decisive factor was not the strength of the aircraft, but the delay between the bomb striking the ground and the explosives actually detonating.
I'd suggest that the pilot survived because the bomb went off way behind his aircraft.
Regards,
