This photo shows the crash of a Navy F6F-3 Hellcat aboard the USS Enterprise (CV-6) in November 1943. The plane's ruptured belly fuel tank caused an instant fire.
The guy climbing up the side of the aircraft, with his boot on the ruptured fuel tank and flames all around, is the Lieutenant Walter L. Chewning, Jr., USNR (Catapult Officer on duty). He is assisting the pilot, Ensign Byron M. Johnson in getting out of the burning aircraft. Both escaped without significant injury.
But, really, the photo says it all.
