The original boat hull C130 would seem to have a few advantages over the pontoon version but since the Air Force is looking at something that is mission specific rather than dedicated it makes sense. Going to have to use the rear ramp to do any airborne operations. I'd be leery of exiting the side door with that extended end of the pontoon waiting to catch either me or the deploying chute. I'm surprised the Navy didn't look into this a long time ago. Perfect for Seal Team deployment.
What's the point of an open door policy if inside the open door sits a closed mind?
