Not only did my PLF never look like the ones I had to do to get past Tower Week, but in my later career I was actually brought out to do my patented "Airborne Sack of Potatoes" PLF as a horrible example of "how NOT to land"!
My landing (on a GOOD day) could fairly be described as about the equivalent of a side of beef being thrown off a truck (traveling at a high rate of speed).
And I made it through Jumpmaster School, too. (Not without some minor difficulty, though- I once managed to just plain FORGET to release a PAE bag with well over 100 pounds of ammunition, radios, etc in it, prior to impacting the ground. It would have made a great America's Funniest Home Video!)
It is amazing, in retrospect, that I have only the knee and shoulder injuries I do, and never actually broke my neck parachuting. I was GREAT in the air- it was just that little landing thingy that got to me... :-)
Damn difficult with a mushroom canopy, to position yourself for a PLF on the opposite leg of the weapons bag. In '67 they never thought about dropping the bag phirst! HELLO!?!
As my Daddy always said "It's not the fall that hurts you, it's the SUDDEN STOP!!
