This weekend I was on a jump where one of the jumpers ended up with both canopies out at once. They were both squares. I think that the main was a Fury and the reserve was a Raven II. I was amazed by how nicely the 2 canopies flew together. They were in a perfect side-by-side formation with no bumping or oscillating. The jumper flew them together for 5 to 10 seconds before cutting away the main. He landed without further incident. Was this normal, or was he lucky? The jumper didn't do anything, (turns, etc.) to upset the status quo while assessing the situation. "Conventional Wisdom" says that 2 squares will wrap around each other in this situation. Somebody else must have experienced this or seen it before, What happened to them? Did they get a wrap? or their own personal downplane? Gives a new meaning to CRW, doesn't it?

The jumper cut away the main and landed the reserve without incident. This was about a month ago, a Manta with a Sharchuter reserve. -- John Bunda * bunda@cs.utexas.edu * {uunet,harvard}!cs.utexas.edu!bunda

It must be fairly rare so far. All I can recall is speculation on 'your own personal downplane', the above mentioned side- by-side, and requests for information if anyone sees it happen. And so it goes. We've added to the sum total of 'what we need to know'. Thanks for the post. Blue skies & soft landings, Mike Spurgeon Internet: mspurgeo@oucsace.cs.ohiou.edu

It's gratifying to hear of two squares out without incident...especially since I replaced my Phantom 26 with a PD193R about 6 months ago. If you or anyone you know ends up with two squares out, how about writing a letter about the experience and send it to either USPA or PIA. I know that one of those groups is looking for this type of report. Don't send a letter on behalf of someone you know...convince them to write it up first hand (of course, it'd be neat to get it posted) -- David Phillips sasdvp@dev.sas.com "They that can give up an essential liberty to obtain a little temporary safety deserve neither liberty nor safety". -- Benjamin Franklin (1759) "Gun control is being able to hit your target." -- Me.
