Jeez Bill, surely you can see that engaging Turtle is futile if the goal is getting him to understand the obvious. Like the rest of American discourse this forum is being dumbed down by the wrong idea that all points of view have value and must be courteously engaged ad nauseam. Turtle should not need to be told what you told him: he should already know it. The reality is that he's playing you just as he plays others.

Hi Jim, While it has been 15 yrs since I had a nice sit-down talk with one of the major players at PD, he said the very same thing. He said that the small canopies registered the highest opening shock loads of all the canopies that they had measured. It is fairly simple physics. Jerry Baumche

Larger canopies have a larger volume than smaller canopies so fill time on a smaller canopy is less. Having worked in R&D at Para-Flite and done many test jumps and drops from small canopies to large the larger canopies opened softer. I think the hard opening problem is related to an out of sequence deployment. If that is the case the solution would be to use something like the free pack strap we used in the 1970s but still put it in a deployment bag. That would insure you are at line stretch before inflation starts and the slider is still in position.

Facts aren't widely used to form opinions and make decisions.

You mean this Joe?
