From uk.rec.skydiving "Just thought you all ought to know: we've got a Skyvan - nice big tailgate for any newbies listening - from Saturday 19th April (Easter) through to the end of the Langar Boogie, which runs 3rd to 11th May. The LET 410 returns around the end of March, and of course we've got our Grand Caravan on site year-round. A total lift capacity of 50 plus a couple of videos! Come and join in!"

Apparently, Will has some "wing suit" experience ;-) Care to share it with everyone? :-D

Very Atom Legendesque. Not surprising considering where half of Aerodyne Internationals staff come from! To be fair, I think that is because the rig is being suspended from the yoke rather than worn and cinched down. That would curve the yoke around the shoulders tightening up the slack.

Attached is a still from the latest ABA video, For A Few Jumps More, of a guy who did BASE in his first four jumps. The first three are PCA'd and he freefalls the A for his fourth, hand-held. Doesn't say that it was done in a day though. Not familiar with the objects to know if it's geographically possible. Unlikely.

Some sum: Assuming from exit to opening is 3000 feet ((3000/53)*60*60)/5280 = 38.6 mph average vertical descent rate Boris has sent some stills from the vid. A flavour for those who can't or won't download the video. He found the opening "especially interesting"!

BirdMan Robert has sent me some video of him, via his brother, flying the new S3 recently at a large legal wall in Italy. He's asked me to post them so I've uploaded them to skydivingmovies.com. There are four files in total; one view from Robert's handcam and one shot from the top, both in medium and large sized files. Medium version from Robert's handcam (3.06 MB) Medium version from the top (4.85 MB) Big version from Robert's handcam (8.85 MB) Big version from the top (12 MB) About the flight in Robi's own words, "The flight were fast and around 53 sec w opening at 300m also I passed the creek and flew paralel w the creek for some time" Absolutely awesome! The shot from the top is most impressive as you get a real perception of him tracking the creek! And 300m is nearly 1000 feet!!! i.e. 1/4 of the maximum available altitude unused! You can get some brief glimpses of how big the wings are on the new suit and it looks a little bit skaty during the initial flight! Robert's brother Boris is trying to send me some stills from the DV that may show this a little better. I'll post them when I get them.

Found this technical article with diagrams and pictures on the Aerodyne website

Are you sure it's this month? A Maxim

Nice video, I was going to say less is more but I think it works ;-) Weridly, Steven Henderson has just uploaded his WFFC edit (36.7 MB) to skydivingmovies.com Phree, can I put your vid up there too?

Gus has sent me some of his data and it's now available here. If anybody else would like their data available on jumptrack.com then send me your files (remember all 3 files - *.MB, *.DB, *.PX from the Jumps sub-directory and zipped up please)

I imagined something like this...

Actually, it's "more than 7 seconds" i.e. 8. Yes, it's on page 18 of the ProTrack manual under Setting the Logbook Totals. You do as you would for setting your jump numbers when you first got your ProTrack. In the Mode selector, page by pressing the Mode button until you reach the Logbook (Totals) page.

I'd like to draw your attention to this post I made and in particular to this graph which plots a helmet mounted ProTrack against two laterally mounted ProTracks for the during the same wingsuit jump. As you can see, the variation is wide, probably due to movement of the head (looking left and right) and moving the ProTrack into and out of differently pressured air. I've just noticed that the time period between the peaks and the troughs is approximately 6 seconds and it's approximately the same on your graph. Six seconds is the period of time that a ProTrack buffers and averages freefall profile data over. I wonder if it is a coincidence?

Nice. From L&B? Typical! :-)

I believe before the ProTrack came out JumpTrack was, and still can be used as, an ordinary logbook program, without the the freefall profile data. Cool :-)

The cable isn't available separately from the software; it's an effective piracy deterrent. Shame on you if you were thinking it would be cheaper to just buy the cable and copy the software and serial code from a friend! L&B are good guys. They'll change your old ProTrack to one with a SLO mode for free so don't try and bilk them for the software. If you weren't thinking that then I apologise!

Gus, too bad we didn't get any skyflying done together; want to jump with you before you leave me in the dust! But I think it might have slowed us down for the £100 weekend and we wanted toget our money's worth! Not going to be back up for at least a couple of weeks though :-( Edit: p.s. send me your ProTrack files and I'll put them up on www.JumpTrack.com!

Just to reiterate, if anyone wants to send me their ProTrack databases (the three files, *.DB, *.MD, *.PX from the Jumps directory), I'd be happy to host them on www.jumptrack.com.Using this website you can chart graphs dynamically online and even overlay multiplegraphs to compare jumps with previous ones.

Andy, perhaps it's time to limit each user to only 1 concurrent connection? Should make more people happy more of the time...

I've recorded the stream and uploaded it to ftp://ftp.skydivingmovies.com/UPLOADS/19434.asf (will eventually move - do we think destined for the /From TV/ or /Tandem/ directory?) Wow, looks COLD! Also looks a bit uncomfortable with the second passenger attached to the Tandem Instructor. When Geoff, Wendy and Sian did it, wasn't the second passenger clipped to the first who was in turn clipped to the TI?

Not the first time. Geoff Woods did this with Wendy Smith and Sian Thompson (early 90s?). Still, would be interested to see pictures and especially video!

Have you tried it there before? I think it's going to be pretty shielded from the satellites by your body and you'll have trouble getting a lock. Think you are going to have to extend the antenna up to your helmet. Also, you'll have trouble getting a lock in the plane. Either sit by the window and hold the unit or antenna to it so it has a clear view of the sky (not under the wing) or ask the pilot to pop it on his dash.

Beer! I'll be at "Langr" this weekend so you'll be able to pay up! If you wait a couple of days, I do believe there will be an article in the next edition of the Skydive Mag with regards to Insurance. The magazine should be hitting your postbox over the weekend. They'll probably be a fair few editions around the DZ. You might also like to check out the previous magazine where I had a little grumble on the Letters page about the attitude of Harrison-Beaumont which may affect your decision to send any of your business their way!

I was going to but he poo-pooed my "squiggly lines" so now I'm sulking :-P Was having a brief conversation with Hooknswoop about this the other day. I've had some good results from OziExplorer which produces a nice track profile, but it seems that the latest freebie version doesn't have that function available? I'm unable to test this as I don't want to lose the version I've got installed if this is true and don't have a spare machine at the moment. I tried playing with the 3D version for a visualisation but with no success. I've emailed the authors to see what they know. I'm sure I posted something about this before when Yuri supplied me with some of his data before I had my own Skyflyer, but I've not been able to find it?! I had attached several pictures of combinations of the track profile. Their production required a little bit of tweaking; manually determing the start and the end of the freefall to trim the graph left and right with the scroll bars, setting a nice scale, as well as vertically. I've attached a couple of graphs generated from Yuri's data which should satisfy Scott/Lou (I thought he was really Lou Diamond Phillips! :-P) where the speeds and distances covered are apparent. Both measurements are for the horizontal vector. A ProTrack download will give you a graph of both of the vertical vectors (I think OziExplorer will only do this for distance not speed).
