I don't know if you're joking or not, but I really did watch one guy who
had
to back off a couple of steps and achieve some momentum to climb onto the
wing of a Comanche.

No, I'm not joking. However it's not completely a weight problem
although that's a good portion of it. He basically grabs the door
frame and pulls himself up into a position where he can get in. If he
ever got into the Deb I'm afraid we'd have to lift him out as he just
doesn't have the mobility.

With that much heft I'd be afraid they might miss the wing walk way
once they got up some momentum.

The guy was overweight, although not to an unusual degree, but had a hip
problem.

However, I strongly suspect that less weight would have helped a lot.
