Marty_d Posted August 2, 2016 Posted August 2, 2016 Fortunately, it wasn't a runway he hit and he didn't end up like strawberry jam... but he DID fall for 25,000 feet without a parachute! US skydiver jumps out of plane at 7,600m with no parachute, lands in net It sent cold shivers down my spine just watching it.
Marty_d Posted August 2, 2016 Author Posted August 2, 2016 Saw that huge gonads. Thanks, but just call me Marty. I reckon his are much bigger than mine. 5
storchy neil Posted August 2, 2016 Posted August 2, 2016 As the planing and calculations would be a bloody nightmare Should have rolled the other way This very senerio was discussed forty years ago but then cranes that size or nets that size wernt around Neil
Marty_d Posted August 2, 2016 Author Posted August 2, 2016 As the planing and calculations would be a bloody nightmare I guess they'd know his weight to the gram and terminal velocity would be known - plus I reckon they dropped a few weighted dummies from a chopper just to test the bugger before he did it.
bexrbetter Posted August 2, 2016 Posted August 2, 2016 Bit silly really, no one can judge an unforeseen crosswind and he landed scarily off center. I wouldn't deny him for having a chute on him just in case - and not that it made any difference anyway, it looked like he had a front chute on to me, or was that some instrumentation or something? 1
fly_tornado Posted August 2, 2016 Posted August 2, 2016 Crosswind? without a parachute? No lift producing surfaces, so no worries 1
facthunter Posted August 2, 2016 Posted August 2, 2016 He's moving with the airmass so the crosswind does affect him. His drag equals weight (closely) and he is still aerodynamic to some extent. I would imagine his terminal velocity in the lower levels at about 140 MPH. He was certainly a fair way off centre and the net would work best on centre. Nev 1

Yes, they did do tests with crash test dummies and one of them went through the net at one stage.
pmccarthy Posted August 2, 2016 Posted August 2, 2016 I reckon that a live human is also a dummy in that context. 3
PA. Posted August 2, 2016 Posted August 2, 2016 When is he going to do it without the safety net? 1 3
farri Posted August 5, 2016 Posted August 5, 2016 Jumping without a parachute, even when you have one. Paraglider Who Fell 150 Feet Says It’s a Miracle He Survived

I would imagine his terminal velocity in the lower levels at about 140 MPH. He was certainly a fair way off centre and the net would work best on centre. Nev Terminal velocity in a flat stable position will be approx 120mph, depending on body shape & jumpsuit. And he's actually highly aerodynamic, just has a very poor glide angle! If you watch a big formation break off at the end of a jump, they all head off in different directions in a sort of starburst, to find a bit of clear sky for opening. That body position, if held, gives a forward speed of maybe 40mph (I think), though at an increased descent rate. Put it this way: it's amazing how much ground...or sea... you can cover when you pop out of cloud at 8000ft to find yourself rather further off the beach than you had hoped. Not that anyone jumps through cloud. Or near water without flotation. Of course....

Landed on the wrong side of the waterline:wink: Ok ok I will go and join phil in the corny corner. 1
Marty_d Posted August 5, 2016 Author Posted August 5, 2016 Ok ok I will go and join phil in the corny corner. I'd be careful about joining Phil in the corner, chances are there'll be a bottle of Barossa's finest in a brown paper bag and the next thing you know you're blinking in bright sunlight and people are tossing coins in your hat... 2

Landed on the wrong side of the waterline:wink: Ok ok I will go and join phil in the corny corner. I'm tempted to an elaborate lie...but okay, so I made up the cloud bit. Depending on aircraft type and position in load, you often don't get to see exactly where you are until you go out the door. And before GPS, the spot (exit point) was eyeballed by the man in the door. It's really neat slamming out the door, my mind used to take 'stills' of that moment, and really good moments could last you to Wednesday, maybe even Thursday of a working week. But just sometimes the man in the door really f***ed it up, and this slam out the door went "Bright blue sky.....bright blue sea, oh wow. Hold on....lotsa bright blue sea...oh sh**......stuff the relative work, assume very best tracking position, pointy fingers pointy toes, flared nostrils, everything else puckered up to f22 and head for that little yellow line over there........ No I didn't land in the sea, but I didn't have much to spare when I hit the beach. The cloud one is an older Canadian story with a bad ending. But I'm not telling that one if you make me go in the corner with that Phil...
