JohnRich 4 #51 January 31, 2005 QuoteKeep in mind that safety/reliability is not always the driving force in gear design. Correct; fashion and what's "cool" are sometimes the overriding factors in what jumpers choose. Quote Share this post Link to post Share on other sites

Um, I think you must mean that it extends vertically higher behind the back. But I don't think it would be as wide compared to an old balloon suit.

Hooknswoop 19 #54 January 31, 2005 QuoteUm, I think you must mean that it extends vertically higher behind the back. Right. And it is more 'powerful'. With a balloon suit it is wider, but not as strong. Either way, a spring loaded PC can/would still get caught in the jumper's burble. Way back when, when double zippered suits were popular, before balloon suits, jumpers put 2 PC's on their mains to prevent hesitations. One would still hesitate, but rarely both. I wonder if spring loaded PC's weren't required if reserves would use them? It would make AAD deployments a problem. Derek Derek Quote Share this post Link to post Share on other sites

Bill Booth said that he thought about designing hand deployed reserve PC, but the AAD made that basically impossible. He also added that it is better for the reserve to be "remotely" operated in the sometime present "panic" mode. Quote Share this post Link to post Share on other sites
JerryBaumchen 1,450 #56 February 1, 2005 And a guy by the name of Rich Johnston (a world record holder) of the Seattle Skydivers, back in the mid-60's, put two pilot chutes in his X-Bo reserve container. Yes, it had a Navy 26 ft conical, also. Quote Share this post Link to post Share on other sites
JohnRich 4 #57 February 1, 2005 Quoteput two pilot chutes in his X-Bo reserve container. What I remember from reading about those dual pilot-chute setups, is that they didn't really work any better than a single pilot chute. They would fight each other for the same air, with each one alternately inflating then collapsing, as the other gained dominance. Quote Share this post Link to post Share on other sites
wmw999 2,555 #58 February 1, 2005 Quotedual pilot-chute setups I borrowed a 2-pilot chute rig from a friend for awhile during my late student career. I think it had two pilot chutes because a. it maximized the lifespan of each of the ragged-out pilot chutes b. it made packing that rig (a barely-extended B4 with cones) the worst pain in the ass imaginable. Wendy W.There is nothing more dangerous than breaking a basic safety rule and getting away with it. It removes fear of the consequences and builds false confidence.

JohnMitchell 16 #59 April 10, 2005 I owned a B-4 with a PC (didn't everyone back then?) Whenever I teach packing now and someone is complaining about a hard to close container, I just think back to those four f-ing cones and smile. Quote Share this post Link to post Share on other sites
