melushell 0 #1 April 5, 2005 what are the average speeds in frefall ? belly Rw groups/ big formations Headdown sit stand tandem ( with/without drogue ) and I am sure the list can go on Quote Share this post Link to post Share on other sites
Amazon 7 #2 April 5, 2005 Quotebelly Rw groups/ big formations Headdown sit stand tandem ( with/without drogue ) Belly depends on my suit. 145 down to 110 RW Groups Bigways.. 60 way at SD AZ was about 115 to 125... one jump smaller way with floatybutts 104 Headdown.. hmm does my 310 MPH speed dive count??? Sit 160 to 175 Stand... big suit 145( balloon suit that inflates.. and funny to watch me in a stand) to 195 in my freefly suit Tandems depends on which TM and what size student..

Tonto 1 #4 April 5, 2005 Perfect speed is being there. Some Wingsuit moments are in the 20's, I think, and the world record is around 500? (Both these are guesses.. confirmation please?) tIt's the year of the Pig. Quote Share this post Link to post Share on other sites

Lowest recorded maintained decent in a wingsuit is 35miles per hour (56kms) -18 point something miles per hour was the lowest recorded instantaneous speed Fastest recorded speed ever was speed diving at 358 Miles per hour (576kms) My Karma ran over my Dogma!!!

Yes, yes I am. I don't really cosider that your "average" skydive. And though his speed was crazy-fast. He did not break the sound barrier. Also, don't forget that the value of the "sound barrier" is largely dependent on the atmosphere. There is no sound in space. My Karma ran over my Dogma!!!

His flight and parachute jump demonstrated that, properly protected, it was possible to put a person into near-space and that airmen could exit their aircraft at extremely high altitudes and free fall back into the Earth's atmosphere without dangerous consequences.

yarpos 4 #16 April 6, 2005 i do love a pedantic discussion if sound is the transmission of pressure waves through air, how can ther be sound if there is no air. you can have an event that had potential to produce sound, but no atmosphere, no sound pedant mode off ....but never for very long steveregards, Steve the older I get...the better I was Quote Share this post Link to post Share on other sites

QuoteFAI NEWS: World Skydiving Record for Distance in Free-Fall Unbroken for 40 Years 01/11/2002 | Posted by JeanMarc at 09:33 AM version française On 1 November 1962, Eugene ANDREEV jumped from an altitude of 25’458 m over the Soviet city of Volsk. Opening his parachute at 958 m, he covered a record distance of 24’500 m in free-fall. Forty years later, this World Record still remains unbroken. Eugene ANDREEV was born on 4 September 1926. A Master of Sports in the former USSR, and holder of FAI Sporting Licence #3812, he boarded the Volga balloon on that first day of November 1962 wearing a T-1-3 parachute on his back. Barograph #506 was attached to Andreev’s harness to register his performance (see pictures below). The balloon took off from the city of Volsk (N 52°02’ E 047°20’) at 07.44 (Moscow time) and climbed to an altitude of 25’458 m. After leaving the nacelle, Eugene Andreev covered a distance of 24’500 m in freefall, before opening his parachute at 958 m. Andreev landed safely near the city of Saratov (N 51°48’ E 048° 12’) at 10.21. (FAI Record file #1623) In Kittinger's own words: Quote"An hour and thirty-one minutes after launch, my pressure altimeter halts at 103,300 feet. At ground control the radar altimeters also have stopped-on readings of 102,800 feet, the figure that we later agree upon as the more reliable. It is 7 o'clock in the morning, and I have reached float altitude.... Though my stabilization chute opens at 96,000 feet, I accelerate for 6,000 feet more before hitting a peak of 614 miles an hour, nine-tenths the speed of sound at my altitude."

courage 0 #18 April 7, 2005 Marco Wiederkehr of Liechtenstein is the only one in the world who has broken 500 km/h in a Speed Skydiving Competition. Bare in mind that this is an average speed measured over 1000 meters, and NOT the maximum. Stan Snigir holds the US Speed Skydiving Record. You may hear about people who claim to have hit a maximum speed of a lot more than 500 km/h, but this is very seldom based on a correct reading by the instruments. In my opinion, it is a lot cooler to be in control over a considerable distance in free fall, doing more than 500 km/h, than being out of control, and perhaps get a false reading and claiming something a lot faster. (Now, let's see who can read what into this post). www.speedskydiving.com Quote Share this post Link to post Share on other sites
goose491 0 #19 April 7, 2005 Quoteif sound is the transmission of pressure waves through air, how can ther be sound if there is no air.. Water will do the trick. Even faster too. (the speed of sound is sorta dependant on the density of the stuff it is traveling through) Quote..you can have an event that had potential to produce sound, but no atmosphere, no sound Precisely. The one and only flaw in Goerge Lucas' films that I can point out without feeling like a complete Nerd... is when ships fly by and explode and such and you can hear them. There IS not sound in space. Joe came close to (or even beat) the speed of sound at earth-surface-level... The speed of sound is slower the higher you go... and the speed of a freefalling body is slower the lower you go. What I had said was that he had not broken the sound Barrier. Listen guys, there was no "Sonic Boom" right? My Karma ran over my Dogma!!! Quote Share this post Link to post Share on other sites

(Now, let's see who can read what into this post). Here's what I read into that... that you assume Kittinger just took a leap of faith and that we all assumed he had no 'control' over the situation. Well, his own words before exit: "Lord, take care of me now" Really though, at that altitude however, I'd say control over your sanity is game one. Just think: The calculations had all been done by Air Force and Air Force alone, the equipment all built by the lowest bidders. He'd lost partial pressure in the suit's right glove and blood pooled in his hand, causing extreme pain and paralyzing it. He should have aborted but continued on without telling ground crew. He reported that his first instinct after having stepped off the gondola (feeling no air resistance and no sensation of direction), was that he had allowed the balloon to go TOO HIGH! He feared he was caught floating in space! (can you imagine? ) Begining a rotation could in itself become centrafugalistically fatal! (lol, I know that's not a word). However, he was still able to turn himself over and confirm that he was falling and not floating. "But when I flipped over and looked back at my balloon, it sure was an eerie sight - the sky was black as night but I was bathed in sunshine." -Kittinger Granted the speeds are wishy-washy if you force someone to give you an actual figure. But the theoretical speed is pretty damned impressive to say the least. I'd say that this experiment was definately a Huge exercise in control. Both Mental and Physical. My Karma ran over my Dogma!!!

Amazon 7 #25 April 11, 2005 hey when you go thru 5500 ft... just go to an arch... and you take off into one MONDO track... all the vertical speed into a LOT of horizontal speed. Then to slow down just keep your arms at your side.. and bring your hands down in front of you like speed brakes on an aircraft,,,, when you feel the force against your hads stop you know you are going slow enuff to go to a nice big stable and deploy.... I learned that the hard way... deploying at 2018 ft at 60 MPH( vertical) and god only knows how fast horizontal I blew 5 lines from my Triathalonand had to chop the mess.... I did not hear my first alarm go off at 5500.. I heard the 2nd at 4400 where I was doing 310 MPH...3rd alarm is set to flatline at 2500... I now use a Pro-Dytter and a Pro-Track in my FULL face helmet..the open face was too noisy and 300 MPH+ windburn SUCKS Quote Share this post Link to post Share on other sites
