Are you sure that escalation is a good thing when dealing with authorities? It's not that they will listen to you and say, "Uh-oh! I've never thought about that! I agree with you, I'm an asshole. BASE is a beautiful thing! You're free to go." As a GC, you're in better position if you don't say anything. You don't have gear on you and it would be nearly impossible to prove any charge against you. But continuing to brag about it on the Internet... only brings more heat to objects. Rangers confirmed that they monitor this forum: "Rangers said... that illegal jumps from other southern West Virginia bridges are not uncommon. In fact, assistant chief ranger Duncan Hollar said, jumpers from all over the world have been known to brag on Internet forums about their unauthorized jumps from bridges within the New River Gorge National River."

In addition to the multitude of these evolutionary suits, there will be revolutionary suits, the suits that will blow your mind away by their aerodynamics and innovation. Special devices will be developed to fine tune the performance to the max. In addition, in WS BASE we'll be flying farther by using special flying techniques. Prepare for the major earthquake! By the end of the year, you'll look back at 2006 and tnink, Was that called "flying"?!

Doesn't HC-7 have optical stabilizer? (vs. Hc-5,3,1 with electronic one.) How does the optical stabilizer perform in the sky? Does is handle quick camera movements well?

Not exactly related to the discussion, but cool stuff anyway related to using the wind. Check this video out. It's non-powered sailing directly downwind faster than the wind. Sounds impossible, yeah? Here is the description of the vehicle, there's a picture of a bigger vehicle on page 10 here, and there's an explanation how it all works here. Cool shit!

yeah, steady wind is paramount for this. Would a paragliding canopy in weaker winds (

Some great ideas here! Here's more. With a big canopy and strong enough wind (~15mph), there is no need for tow, simply anchor the rope and kite yourself up. You payout the rope as you go up to maintain the angle of tension. (your end of the rope is not permanently attached to your quick release, instead it goes through (the excess rope just lies on the ground) and you control it with a tension mechanism.) Go up a few hundred feet, cutaway, turn downwind and have a nice little cross-country flight. Now imagine you go up a big mountain (not WS BASE-jumpable) and launch yourself this way a thousand feet up with a packed rig and wingsuit, cutaway and fly. The launch canopy will fall to the ground (will need to invent something to keep it deflated while it's tethered). Land, hike up, repeat. Totally autonomous wingsuit mountain flying.

you'll need to fly well in front of the front, where the air is still still. not exactly surfing, but still... Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio

For the single would-be coolest moment in the life, how about this: Plant some dynamite on a big steep mountain in severe avalanche conditions. Jump from a plane in wingsuit and trigger the avalanche at appropriate moment. Surf the front "wave" of the avalanche. It's do it or die, no doubt, but cool like hell! The visuals will be amazing. I guess, I got inspired by this. Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio

If you're going to do your first base jump at BD, you want to go handheld there. So a good exercise would be imitating a handheld 2s delay. Exit looking above the horizon (~30-45 degrees) and try to put your body in perfect horizontal or slightly head-high position by 2 seconds, then "throw" forward and up an imaginary PC in your hand, while maintaining stable body position for at least another 1.5s (time to linestretch & inflation). Out of group of 6-8 jumpers, exit first. You want to imitate solid launch point. Balloon gives in when there's not much weight in the basket, so the launch is "soft" in this case. Burner has a special platform outside the basket, ask him to install it. It will give you better imitation of the launch platform at BD than the soft edge of the basket. And tell Mr. Burner Yuri said "hi".

Here is another illustration of effects of wingloading in WS BASE. We apply wingsuit equations to two jumpers of the same size, but different exit weight: 180lbs and 260lbs. They both have L/D=2.5 (the model assumes that it's constant throughout the flight for simplicity). The lighter jumper has sustained speeds 100mph forward, 40mph down; the heavier jumper - 120mph forward, 48mph down. (The speed is proportional to the square root of wingloading: 48mph/40mph = sqrt(260lbs/180lbs).) As can be seen from the graphs, the lighter jumper has a significant advantage in distance covered. The most dramatic difference happens for relatively low walls with 2000ft of usable altitude: the light one flies 3000ft horizontally, while heavy one only 1500ft. The heavier jumper's planeout kicks in later, but lasts longer. At 3000ft of usable altitude, the difference in horizontal distance reduces to about 800ft. At 4000ft, the difference is about 1000ft and stays constant after that. The average glide ratio for such a flight, if we subtract 500ft for starting to fly, will be 2.3 (8000ft/3500ft) for the light guy and 2.0 (7000ft/3500ft) for the heavy. So if you're heavy, you naturally suck! On the other hand, if you're heavy and flew to the same spot as a light guy, he sucks (his L/D is lower). Now, what's that Deadmanwalking's big wall diet?

Did you inspect the PC/pouch to see what was making the pull hard? There must be something, it's not like ZP and spandex got cemented together. (Unless, of course, a beautiful Russian girl got mad at you and injected a tube of KrazyGlue in there! Russian girls kill with style, no doubt! ) What makes the pull hard is usually a part of the bridle and/or mesh getting outside of the bundle, which makes the stuff that's still inside the PC expand when you pull. If you keep all the "stuff" inside the PC (with a good margin) when you pack it and insert it, this pull-expand action wouldn't happen. Another thing, when inserting a PC which is extracted at 90 degree angle (leg pouch on Vampire), pay attention to how the bridle stack is oriented. If it's oriented "ribs" up, it can make the bundle very stiff. Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio

An interesting visual effect happened to me recently. The uppers were 80-90mph that day and there was a thin solid layer at 8K, so I couldn't see the ground. This high flat layer accentuated my fast horizontal speed. I go through the layer and BAM! - see totally still ground! It felt like an instant stop. Very cool effect! Next time I'll try going through the layer downwind, it'll be like a space warp!

What happened to the world?!? It's like somebody unleashed the dogs in 2007! Everybody is talking about performance, glide ratio, lift and drag, polar curves, the best and fastest suits, writing equations and pouring GPS data... Crazy people... Go flock or something! 2007.

The guy in teal V-2 has big creases near shoulders/vents, just like on my V-2. The wing doesn't seem to be solidly inflated (it's bowed and smooth at the bottom, but that's because the air is hitting it at 45 degrees and he's cupping the air... just like monosurface wing i.e. Prodigy's is smoothed out by air. From the top view, there doesn't seem to be a good internal pressure.) Can he share his observations about inflation, fit, and maxing out? P.S. Watched the video again, the guy in red V-2 - same problem. The top closeup view shows terribly creased arm sleave, choked vents, and poorly inflated wing. Never seen anything like this in other suits! I guess, a trip to a local taylor is in order. Sad! But on the other hand, the type of performance I've experienced in properly balanced (although creased and poorly inflated) V-2 totally blew me away! It's when you can no longer see where you're going, you just see the ground and clouds pass by below you. You have to lift your head up and arch to see where you're going, and that destroys the glide, so you don't do it often, and that's scary. Flying at canopy glide ratios is scary and beautiful!

Ok. I'm confused. Was Phi designed to have L/D = golden ratio = 1.618...?! Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio

For those who knew Patrick De Gayardon or were around that time, what kind of glide ratios he was getting in his first ever ram-air wingsuit? Judging by the angle of smoke trail in this picture, he was not far off from today. (It might have been a planeout; in this article he mentions that he would sometimes intentionally gain extra 20-25mph to temporarily slow the fallrate. He does mention "I also used a barograph, an airspeed indicator and a GPS." And another history germ: "In Italy, I could make a 32 second delay. The wings offered me 1100 m of altitude. [....] I did the last jumps with a stiletto 135, no more need for a BASE jump rig!" ) Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio

Placing the intake where the speed is the highest and pressure is the lowest will destroy that low pressure since the air has to be stopped, and thus destroy a lot of lift. Jet inlets and ram air inlets serve different purposes. Jet inlets' goal is maximum throughput. They "cut" through the air without creating any stagnation, thus affecting airflow very little. Once the air is in, it's not let to stagnate, it's sucked in by the compression turbine. Ram air inlet must generate maximum pressure from limited airspeed. Pressure is maximum at the stagnation point. That's where the inlet should be placed. Placing several small inlets along the arm disturbs airflow over significant area. One inlet near shoulder is more efficient. But does it need to be a scoop? In current designs, a lot of air is waisted: from the scoop, it flows not only into the wing, but into arm sleeve and body as well. But if we make the inlet deliver the air to the wing directly, with wing chamber isolated from the sleeve and body, then very little throughput is needed to maintain the pressure. (this is for high-performance suit; for aerobatics, the throughput should be high enough to quickly replace the air expelled during fast maneuvers). If the leading edge is separated from the arm by means of inflated tubes or semirigid foam, this gives us space to place a tube-like, not scoop-like, intake which points directly into airflow and pumps air directly into the wing through a channel. With airtight wing, such an inlet can be made small - 1 inch in diameter - and will disturb very little air. Its angle should be optimized for best glide AoA. Such a suit would suck at stallflying, though. Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio
