  1. We are actually making the same point about "once at terminal". I also thought about the focus thing… but not fully convinced by that theory. More inclined to go for the "relaxed" vs. "tense" explanation. -- Be careful giving advice. Wise men don't need it, and fools won't heed it.
  2. Just don't do public transport… I once took the train to Picton, then that's still like 10k from the dz, couldn't get a cab, didn't find a ride, and in the end it took quite a while until a nice jumper had the time to leave the dz and come fetch me. As you become a regular at Picton you'll start meeting people to carpool with - it's a super nice community. -- Be careful giving advice. Wise men don't need it, and fools won't heed it.
  3. Yeah, I know it's a limited time and probably too short to pass out, –but even if not passing out–, if one stands on one's head "on the ground", the discomfort is noticeable immediately, and I haven't heard of anyone feeling this while flying head down. -- Be careful giving advice. Wise men don't need it, and fools won't heed it.
  4. It is quite obvious to me that the blood does not rush to the head of head-down fliers, because otherwise we would constantly have people fainting and this would be a comfort and safety issue. However, when I was asked by a friend WHY this didn't happen, I could not really find a convincing explanation of the physics of it. TUNNEL FLYING How is being "on your head" in the tunnel different from being "on your head" in the room next to the tunnel, in terms of blood weight/acceleration. Why can the guy outside the tunnel only tolerate it for a short while and get a red head, while the guy flying in the tunnel doesn't experience the red head? AIRPLANE JUMPS During the acceleration phase of an airplane jump, one could say it's conditions similar to zero-g. However, once in terminal velocity, the blood from the body would still "rush down to the head", wouldn't it? As stated above, clearly it is not the case that blood rushes to the head on head-down, but WHY? Anyone who knows what they're talking about care to explain the physics of it? -- Be careful giving advice. Wise men don't need it, and fools won't heed it.
  5. I don't post on dz.com often anymore, but Feb. 8th is a special day in my skydiving career... In 1992 I jumped for the first time in Celaya, Mexico an AFF with just one instructor from a Cessna 182 from 6,500ft. In 2006 as part of World Team '06, at Udon Thani, Thailand, I took part in a big jump with 399 others in the formation plus over a dozen cameramen and women from 5 C-130's "Hercules" form 25,500ft. Both seem like yesterday, even though I've more than doubled my age since Feb. 1992, and almost doubled my jumps since 2006. Best regards to all my WT buddies around the world! Looking fwd. to the record being broken soon-ish! -- Be careful giving advice. Wise men don't need it, and fools won't heed it.
  6. I once had the phone ring on me under canopy, but it was in my shorts pocket under the legstrap, so I could not answer. I think I would have otherwise. Did return the call first thing after landing. -- Be careful giving advice. Wise men don't need it, and fools won't heed it.
  7. I have nothing but good memories of Michael from various bigways including World Team 2006. It was a pleasure sharing the skies with him, and I am happy to have met him. RIP -- Be careful giving advice. Wise men don't need it, and fools won't heed it.
  8. http://www.theworldteam.com/10_11Skydives.htm The World Team's webpage has been updated with a lot of new info, including formation designs, sector captains, dates. The new design has a 60-way base with a 12-way star in the middle, and the 1st row of whackers for each sector (a row of 3). To the base are attached 12 whacker sectors with 36 or 37 jumpers each. Each whacker sector is made up of 7 rows of whackers (not counting the 1st row of 3 that belongs to the base). The whackers rows are either (4-4-5-6-6-6-6) or (4-4-5-5-6-6-6). But seriously, why are you reading this text description? Go see for yourself!
  9. As I stated in my original post, both him and me tracked off in a direction away from jumprun, which indicates that after being in freefall for a certain amount of seconds longer than their group, we ended up sharing roughly the same column of air. Given that we were first and belly, and they were second and freeflying, the only explanation I can come up for this to happen is if either or both groups didn't fall on their column of air and flew a significant distance along the jumprun towards the other group. I don't think that winds alone could have put one group overtop of the other. Try it out yourself with John Kallend's model. I was watching other loads and separation between groups had been and continued to be good. Our group I'm quite certain didn't slide over towards theirs, and I did not ask them whether it could have been them. I don't know if they were sitflying, head down, or their experience level. -- Be careful giving advice. Wise men don't need it, and fools won't heed it.
  10. Firstly: you are right - I never assigned blame solely to them. However, if you go by everything we've learned here, if a group of freeflyers leaves after a group of belly fliers, and leaves a reasonable separation, with their extra "throw" during the first seconds of freefall, that separation should increase. It would take a hell of an upper wind to elliminate this separation (try it out yourself with John Kallend's model here.). So surely this had to do with the way the group(s) flew towards each other along the jumprun line. And this is where it gets scary... because you cannot control every person in the plane and how they will fly. Hence an added awareness (/paranoia) is not a bad thing during trackoff. And that added awareness, in my case, comes from reading here, and knowing that there WILL be dangers out there, some of them out of your control. -- Be careful giving advice.

  11. In other words... "To be old and wise you must first be young and stupid"
  12. Yesterday I jumped in a 3-way belly group, followed by a 3-way freefly group. The lower winds were very light - could be considered calm. I don't know what the uppers were doing. The freeflyer group after us say they gave us at least 6 seconds separation out of the skyvan. Come pull time, I am starting to track, and to my surprise, about 600 (?) feet lower, and in front of me, right in my tracking path, tracking in the same direction as me (90 degrees from jumprun) is a guy waving off, dumping and soon after his inflating canopy. So I evaluated opening right there and then, but opted to change my track direction and avoid the opening canopy. Then I pulled making sure I'd be open below him. When his canopy finished opening it started flying towards me, so having ensured the vertical separation was a good thing. I think he must have been surprised when he saw me so close! (maybe 150 feet horizontal, 100 feet vertical separation when I was open). On the ground I had a very civilized discussion with all three freeflyers in his group, and they agreed that they should have left more separation, but were also surprised at the outcome. I am still not quite sure how the drifting in freefall happened that I ended overtop of him. Any ideas? I believe that the incidents forum is responsible for the good outcome here. My awareness level to immediately look for people and canopies below me during trackoff is probably higher than most people's - and I owe that not only to bigways, but also to reading about incidents and near misses, as well as the endless discussions about exit order and separation. So a collective thanks to all of you who contribute to dropzone.com!
  13. Thanks for the pics!!! I am so glad for you all - must have been a very cool event to take part in. -- Be careful giving advice. Wise men don't need it, and fools won't heed it.
  14. when i read a post like this, i ask myself, why did i choose to come live in australia!?!?!? from mexico a weekend in spaceland was an easy thing. even from germany it was a fairly doable thing (but expensive and a couple of days more to take off work). but from sydney... between costs, jetlag and days off work it gets a lot more difficult. good luck, and craig, please say hi to friends for me i sooo wish i was there. it was painful to decline this one, and it's painful not to be there. -- Be careful giving advice.
