The Herc is a very robust airframe. That musta been a quite the hard 'landing'.
That's what I was thinking. It must have been an autorotation type landing. What I understand the wings will stay on even after they've flexed down and hit the ground.
I was working Dak To (huey driver) in November of 67 when a C-130 hit one of those big Cats (D-50, I believe) that was pushing dirt for a runway extension. One of the main gear assemblies squarely hit the top of the dozer blade. It moved the Cat about 50 feet and sadly the operator died on the way to Pleiku. There were landing gear parts strewn hundreds of feet beyond. The "Ever Ready" Herc kept on tickin' and stayed in the air and made a run on landing at Cam Rahn Bay AFB.
Three C-130s burned on the Dak To ramp around that time when the fuel and ammo dump was hit. The crews had to unass the running aircraft as burning material ignited their aircraft. Not much left when after they let 'em burn.
