peggs82 0 #26 May 12, 2007 Replying to the OP.... Last year at Summerfest at SDC, a student cut away, tossing her handles. Apparently the sky wasn't so big for a fisherman below, as it hit him on the head. I never heard any follow up to it, but I do remember when the cop came in with the handle. Also.. Just 3 weeks ago while walking to the plane, a helmet impacted just 10 feet in front of us. It hit square on the runway and literally bounced 20 feet back into the air. It was one of those odd situations where everyone had been standing around and I thought to myself, "why aren't they walking to the plane?" .... Had they been walking to the plane I am absolutely cirtain one of them would have been hit by that helmet.... ps. the helmet was a Z1 that experienced a violent riser slap on deployment (I am not convinced she had it buclked down or not). Helmet must have fallen 3,000 feet... anyone know what terminal velocity of a Z1 is? Quote Share this post Link to post Share on other sites

hookitt 1 #28 May 12, 2007 QuoteI could see a camera helmet doing some serious damage to somebody if they were struck in the right [wrong?] way. That said, it's not like somebody could put a little "reserve" round in their helmet in case of a helmet cutaway. Premature deployment = decapitation. Sure you can. It has been done for a long time now. I don't remember the name of the helmet and don't know if the same company even makes helmets anymore. The Canopy was stored in the helmet, not outside so it can't deploy unless the helmet is taken off. The canopy in the helmet just layed pretty flat on the top of the head where the impact foam is. A release system cutaway the chin cup and you held it as you tossed the helmet. A short lanyard was attached to the small d-bag the round canopy was in.Optionally the lanyard could be attached to the chest strap. Remove the helmet and throw it. Jesse Rodriquez, previous owner of the dz in Marina CA, had one. He actually lost one from a super hard opening and the camera filmed the entire descent then focused on the grass when it landed. Smaller Skysurf boards have a recovery chute contained on the board itelf. Larger light boards don't have recovery chutes. The canopy in the helmet just layed flat and on the top of the head.My grammar sometimes resembles that of magnetic refrigerator poetry...

MB38 0 #29 May 12, 2007 FTP = Flat Top Pro That's about what I've been thinking with mine. The PC would be inside of the helmet where it couldn't get out unless the helmet was removed. That said, in a severe entanglement situation, I could see a deployed PC/bridle in the helmet causing big problems. With a bad entanglement, the helmet may not immediately leave the jumper. There are lines and fabric everywhere. Suddenly adding something extra to the mix could make everything worse. Worst case scenario, what if the helmet only came off by a foot or so? It's still right next to the jumper, the bridle slips down around the jumper's neck and... So what I'm trying to put together is something that will more or less "delay" the deployment of the PC once the cutaway handle is pulled. In other words, it stays as a closed system for a few seconds after it's been removed. If the jumper is low enough that the delay is too great... well... they have other [more important] things to worry about. It's not a product, just me messing around. Anyway, I'm sorry for pulling the thread astray.I really don't know what I'm talking about. Quote Share this post Link to post Share on other sites

Helmet must have fallen 3,000 feet... anyone know what terminal velocity of a Z1 is? About 50 mph. Z1's falling off are actually pretty common. I am impressed the pro track still worked after impact, though. Quote Share this post Link to post Share on other sites

Several times it came halfway off. During the Texas Women's Bigway record last year, the helmet was kicked halfway off on exit. I shoved it back down but didn't notice that the visor was up. I had to hold my slot without a visor for the entire skydive. It makes me grateful that I had a helmet on and wasn't hit on the head.

I have read from time to time about shedding gear such as a camera or a camera helmet to clear an entanglement during freefall or canopy flight.

I realize that your question focused around hard (fast falling) objects, but ANY object should be a consideration... My DZ is along a road. I like to do intentional cut-aways.
