I found this on the web. What do you think or know about this? Quote: "CHARITY parachute jumps are costing huge amounts more than they ever raise because of the cost of treating accidents." I know that it is an older article but it would be nice to discredit the statement in another web forum I´m involved with. Thanks in advance clicky

As the first to annouce the PC oscillation theory. And having worked on other methods of deployment in the field of BASE, I can say this: Extraction speed is what matters. With low extraction speeds, momentum plays a major role in the heading. Granted that I was dealing with much lower extraction speeds than are normal for common BASE jumps. I personally don't think one would get this on a common BASE jump. Because the PC must move into the windline to get the drag to deploy the canopy from the container. Factors that affect one at this moment are the windline relationship to the shoulderline perpendicularity to the windline or lack thereof. Hope this helps. take care, space

I disagree, it was a bad call to jump in those wind condititions in my book for myself. Fark canopy control. I don't think that I would be able to get out of that situation myself. But I do think that I would be able now with my experience not to put myself in that situation unless it was an exceptional object. take care, space

I would consider that "Poor Judgement" or "I knew the risks and it all worked out ok in the end and was therefore worth it."It was only a 90 offheading and he still didn´t have time to recover. take care, space

Check out this site and free download. It is quite excellent. I think you will enjoy it. Airfoil CAD stuff http://www.surfplan.com.au/sp/ take care, space

I think this only happens at line stretch so it is not that critical. I've been present in Norway when a jumper who planned on opening high, over delayed with an unreinforced large PC and blew it up but never noticed it until after landing. I had one on a skydive same result. take care, space

22°57′8.7″S, 43°12′42″W

Yep, I was thinking that the request wasn't very wise. A simple seach just turned up 75 hits. I half expected to see coordinates from some place far away as we have a jumper apparently who doesn't know how to search the forum and apparently doesn't want to deal with the Locals. It's crap to the locals when some jumper from thousands of miles away just gives up the beta to anyone. In fact, it's just plain disrespectful. There is a great resource there as you have said. "The Locals". When I first jumped there, there were no local Locals. It took us 2 trips just to sort out where the exit point was. A few bad landings to sort out the winds. That kind of "scoping it out" for the ITW went out before the turn of the century though there are many of the peaks of the Alps (300,000) that are as yet unscoped. Work hard to open a site and one will understand the negative responses about seeing the site publicized, GPS'd, on TV and such. Good luck to the original poster. Take care, space

Which line would that be? Who drew it?

So what if one jumps there to dial in their canopy for slider up subterminal? The reason for me would be to avoid that slippey slope somewhere less forgiving. I feel that if we all approach an object with the respect that you deem necessary for you, then the advancement of the sport would be greatly compromised. I do agree somewhat with you about respect of BASE sites. But like the split thread about when to quit. I quit when I decide to. Not by anyone else's opinion on when I should. Albeit, I've been around and seen more than most jumpers. The tag that makes this sport one of the greatests and one of the most dangerous is the fact that one can make one's own decisions about if it's doable or not. No S&TA to say it's too windy for you. One has to think for themselves in this new environment without speed limits. This is where I see the danger of the sport lies. Too many authorities keeping too many away from the vicinity of the edge so when they do venture into that zone for the first times that is when they are most likely to pay the ultimate price. This brings up to me what is the best way to learn where the edge is. Through, teacher, instructor, trainer, mentor, or oneself. Once again it is up to the individual and that individual will certainly reap the rewards or suffer the consequences of the decision. Think about this disjointed post I am making and realize that there may be a lesson in it. take care, space

I think that if: a. Released riser is away, you would then be flying in a slow turn and sinking fast. b. If the released riser was being kept near the other riser due to the slider, you would be in a fast turn and sinking fast. take care, space

See ya there, take care, space

ummmm, okay, I'll bite. What corruption do you mean? I saw no ref to it in your post other than the title. take care, space

Keep it in the context from my first post please. Did you see my attachment from the first post in this thread. Would you say that I am incorrect in stating that “Convergence clouds over the peaks are an obvious sign of the Ora wind”? Would you say that these are not Convergence clouds? If so, then why? The fact is that if these clouds are over the peaks, there will be a honking valley wind. Me thinks I/you is confusing colliding and converging. Feedback please take care, space

What are you sorry about? Using different words to say the same thing as I? "Sorry... but all cloud is formed by air rising and the moisture condensing out at altitude. " "Convergence clouds are a result of warm air rising to an altitude that the moisture becomes visible due to the cooler and thus less humid air" If you think about it, all thermics are a result of minor convergences. Please explain why clouds hang above the peaks on a fair weather day. take care, feedback please space

Low pressure systems are the crap. This creates an ascending air, sucking in the moisture from the sea, creating a "from southerly" flow causing rain on the rising terrain and very strong winds at the Austrian bridge,(40 - 60mph). So if there is a low and you have rain at ITW with a "from southerly" flow, you should try chatting up Nadia and Patrizia at the Bar instead of trying the bridge. Any dynamic wind from right to left on the exit point to 600m below is a no go. It makes a bowl of turbs that is very difficult to get out of. take care, space

Convergence clouds are a result of warm air rising to an altitude that the moisture becomes visible due to the cooler and thus less humid air. @ Mac, . "I maybe mistaken but I thought convergence clouds are created when dry and moist air meet, I assume that due to the body of water at one side of the range will mean that this is more common at this site? So if convergence clouds are seen this means there is an obvious meeting of air moving up the valley to meet dryer air from the.." The Convergence clouds indicate thermal activity and the air feeding these thermals are the "Ora". High pressure systems, This is a descending air mass of cooler, denser air. stocking up on millibars to feed the thermics, The Ora is a surface wind, and since ITW is at the south of the Alps the air mass will flow down to the sea creating a flow from the North above the surface Ora winds. In these conditions one must fly in the wind shadow of the wall on the left but still be prepared for the wind direction change at 200m +/- 100m.. take care, space

Here is a diagram I drew trying to explain the "Fair weather" winds in the ITW Valley. Feel free to critique. Have fun, be careful, take care, space

Not only you, but all are out of line on this thread. Pay the packer to teach you how, duh! take care, space

Can anyone post alink or some text that I can find it and view it with "firefox"? thanks in advance. take care, space

I think that those who threw stones should check to see if they have ever had photos/videos of them BASEing on the internet. If they/you have, then you should bow out of this disscussion gracefully. To blame Jeb for bringing BASEing to the attention of the authorities when on your websites show you doing the same thing reeks of assholism. Whiskey tango foxtrot? take care, space

Go screw off on your own threads guys, please. If it's not about what the title of the thread says, go get your own. is this too much to ask? I got my thread, go get yours. Thanks in advance you thread splitters. take care, space

I don't think so. I think I learned it from a jeans falling apart working on my car also.

To the 3 jumpers and any others that are down there at ITW, here are some tips: Tip 1, Ground crew with radios or telephone contact. You can ask someone around the packing area before you go up. If this is not possible, then put off your 2nd most experienced as a wind dummy. Pay attention to his flight and you will get great feedback whether to jump, On which way to fly or which way not to fly and on which way to land or which way to not land even if he doesn’t have a radio to contact you. Tip 2, Ask the local jumpers about the expected wind and weather conditions. They will have the best idea on what to expect. Tip 3, KNOW the ORA wind. If anyone wants me to, I will explain it so that one can understand what causes it, when to expect it and also how strong it is likely to be at which time of year. Tip 4, Know the DYNAMIC winds and their jumpability and associated flight plans. If anyone wants me to, I will explain it so that one can understand what causes it, when to expect it. Just take care, Please, space P.S. Nice to see all of you down there again, Hope to see you soon!
