Well, let's see...: Reserve out of the bag, with Skyhook: 0.5 sec.: http://www.relativeworkshop.com/images/pdt_skyhook8.jpg Reserve out of the bag, with Racer: 1.6 sec. (DOES NOT matter that they packed a reserve the way it INFLATES in the remaining 0.5 seconds!). Let's talk about the 'reserve out of the bag' time, NOT total opening time (reserve container does not control the canopy inflation time!): http://www.jumpshack.com/portal/content.asp?contentid=738 . . . The ABOVE opening would hurt you at best at terminal (same as seen in Racer ad on 'BreakAway' video). One major manufacturer told me that they packed a wet reserve (which opens quicker) and that they had the main front risers locked in a permananty "pulled down" position to have the higher initial airspeed before the cutaway. Another Racer video: http://www.jumpshack.com/portal/content.asp?contentid=750 (looks like a more "normal" inflation, but still far away from Skyhook). More info on Racer claimed "64 feet total reserve deployment distance", from this post down: http://www.dropzone.com/cgi-bin/forum/gforum.cgi?post=1583207#1583207 and these posts: http://www.dropzone.com/cgi-bin/forum/gforum.cgi?do=search_results&search_forum=all&search_string=Question+about+Racer+rigs&search_type=AND&search_fields=s&search_time=&search_user_username=skydiverek&sb=score&mh=25

Will not, or may not? Big difference. From Bill Booth: "Let me clear up one myth right now. The free bag system WILL NOT pull your reserve bag out of its container in the event of a horse shoe malfunction. A horse shoed 16 foot long, 2 inch wide, free bag bridle generates only about 2 pounds of force on the bag at terminal velocity. Most reserve canopies weigh over 5 pounds, not counting force required to extract them from the reserve container, especially if the main container is still closed. What the long wide bridle will do, however, is stabilize the bag, (if you reach back and throw it out of the container) so that it won't tumble through its own lines as it deploys. So, if you ever experience a horseshoe malfunction of your reserve, don't just lie there and wait to hit the ground, sit up until you feel the reserve bridle hit you in the back of the head, reach back and pull on it until the free bag is out of the container, and then let go. The drag of the bag itself, helped out by the bridle, will then carry it to line stretch. I put out a film about this about 15 years ago, but a lot of people seem to have forgotten.". ------------------------------------------------------------------------- "In my tests, a horse shoed freebag bridle pulls only about one pound at the freebag end. Pockets on the bridle don't pull much more, and certainly not enough to pull a freebag out of a modern container. This is good, because the last thing you want during a pilot chute hesitation (common on internal spring-loaded pilot chute systems) is for your bridle to pull your bag out of the container and above the hesitating pilot chute. Reserve totals are rarely fun." ------------------------------------------------------------------------- "Question: So why do we have 2" bridles in the first place? Answer: Para-flite started it over 20 years ago. When they came out with the first square reserve, the Safety Flyer, they decided to "tinker" with a lot of other things too. The "free-bag" with its bungee "safety stows" and 2" wide "anti-horseshoe" bridle was the result. The Safety-Flyer was marketed with the Swift container system which had no pocketed corners. As a result, when you pulled the ripcord, the bag would simple fall out of the container. When they drop tested this combined system with a built-in "horseshoe" malfunction and a tumbling (unstable) dummy, the bag would simply be ejected from the container because of centifugal force (angular acceleration) and be pulled to line stretch by the force of the relative wind on the bag. The super long bridle allowed the lines to unstow, and the freebag allowed the canopy to open. The 2" width merely provided stabilization so that the bag did not tumble through the lines as they unstowed. The anti-horseshoe system worked in those test conditions. However, as stated earlier in this thread, it will not work with a stable jumper using a modern piggyback system. The long, wide bridle has persisted out of inertia. i.e. No one wanted to go against an existing, "proven" system. Even though, I suspect, the wide bridle helps create and lengthen pilot chute hesitations, because of the drag it creates in the burble right above a stable jumpers back on initial pilot chute launch. I have made one change recently, however. I had to shorted the bridle a bit to make the Skyhook work correctly. I kept the 2" width because of the stabilizing effect I noted above." --------------------------------------------------------------------------

OK, so it is known and confirmed by Bill Booth that current reserve bridles will NOT extract a freebag in case of reserve horseshoe. Why not make them wider then? Like 10 inches wide? Would they be too heavy then? If not, why not?

Does every ZP canopy has low-cfm ribs? No. 95% of ZP canopies are ZP ONLY. BTW, do F-111 ribs make the packing easier (letting you "squeeze" the air more easily)?

I remember that. That was in around year 2000. He cut away and pulled his reserve. The cut away main traveled UPWARDS and took the reserve slider back to the top of reserve lines. Mike said he had had only 2 out of 7 cells inflated. He hit some tall trees in that configuration. Mike said he would NEVER cut away from the pc-in-tow again. Interestingly, next time he had a pc-in-tow, he elected to CUT AWAY. Post about this here: http://www.dropzone.com/cgi-bin/forum/gforum.cgi?post=992683#992683

LOL, beautiful, Bill.

Best thing is Kittinger had only like 30 total jumps when he jumped from over 100,000 feet .

But... how do you cutaway your first reserve, if it has, let's say, a nasty spinning malfunction?

343 mph was an AVERAGE speed over 1000 meters. Therefore, his MAXIMUM speed was higher that that.

That must be the most cheesy website I have ever seen...

I think this one is great, Bill: "Superior Parachute Systems" Bart

Wow, that looks like some medieval items of torture ! But seriously - thanks for the research! We would love to find out more!

This is the end result of the tandem pair hang-up over and under the tail ... (Attached). There was a great pic in Skydiving magazine from below (camerman persepctive) of the tandem pair dangling from the tail.

In court the company is not allowed to say that is has no insurance. But it is difficult to hide your name

There is United Parachute Technologies now

(See expamples attached). When google ads are displayed on this site, sometimes they have a WHITE background, and sometimes a BLUE one. I think that with the white one the ads look "amateur" and cheap. The blue one is much better, i.e. fits the dropzone.com color theme perfectly. Unfortunately, 80% the ads are displayed, they are displayed with the ugly white background. Can you make all of them blue? Examples attached.

Are you sure you did not mix grommet types with weight? I always thought brass was lighter ... Does anyone know the weight of Aerodyne's "new super-lightweight stainless steel" grommets? They are mentioned in Pilot ads.

Flight Concepts reserve does not have stabilizers.

Rob Harris? BTW, JumpShack has/had a cutaway rig(s), too.

Similar was done by Troy Hartman in MTV's Sensless Acts of Video.

And the leg strap adapters are ony ratetd at 500 lbs each, right?

Skydiving magazine wrote that there was a French company that was bulding rigs with FOUR rings.
