On whether Cooper survived the jump... On any jump made, the odds are against that the person goes in. But occasionally they do anyway, so I suppose anything is possible. But we don't know how Cooper fared, so we look at the situation and consider what is likely to have happened. Robert99 posted some scenarios that I think are unlikely. R99, I'm not bagging on you, I don't know you personally, I'm just giving an objective take on your suggestions. Not necessarily. Cooper was a smart guy, I would guess that whatever he tied to himself, he tied tightly and securely. With the back bailout rig and the money tied to his front, that wouldn't have been too much different than the typical sport rig of the day, with a back main and front-mount reserve. Freefall stability is kind of like learning to ride a bicycle, in that there is a subtle balance point to it. At first it can be hard to control, but once it 'clicks', it's really not hard. And like everything, some people take to it quicker than others. If he had prior freefall experience, the exit would not have been hard. And if he didn't, and he did tumble, again, he's a ballsy guy, I'm guessing he would keeps his wits about him enough to pull. Not at all. Many people have deployed while tumbling and gotten open just fine. That spring-loaded pilot chute comes off your back quickly and takes the canopy with it. If you're gonna get tangled up in anything, it's most likely going to be the bottom part of the lines. And when the canopy opens, it's gonna flick you out of that like an errant yo-yo. You may end up with line burns, but you're most likely going to have an open canopy. Parachute malfunctions are pretty rare. And of the malfunctions that do happen, total pack closures are very rare, and so are high speed streamers. Most malfunctions that do occur on rounds are slow speed, like line-overs or partial inversions. Maybe a bit higher rate of descent and less control than you might otherwise have, but usually survivable. I think it's highly probable that he survived the jump. The concern I have, as I stated before, is whether he was injured on landing and able to hike out.

I'm sure there are still a few of us out there. Skydivers from the 60's and 70's. Team photo - Northern California. I'm the one with the cast. I remember most ot the faces and a few by name, John by the prop, Jackie Johnson (Jerry Johnson's wife) in the middle, Stash second to end in middle row/black hat. What fun we had. I stayed in the sport for about 8 years and loved every minute of it. Just wanted to share.

More research tells me that the correct term is one word. coronavirus

I've bruised my heel before hang gliding. I've broken a leg playing football. The heel injury was far more painful. Yeah if the risk of a jail cell for fraud didn't worry you. You could take off the jumpsuit, leave the DZ and tell the attending physician that you had a hard fall at home. An ordinary broken bone is not very life threatening IMO. A multi-compound broken mess of bone protruding from the skin. Might put the insurance issue aside.

It sounds like someone decided there were enough differences to make the patent non applicable. The patent holder disagrees. Either they negotiate, litigate, or drop it because it will cost to much to pursue. This kind of dispute is common enough, and inventors feeling screwed over is as well. Sometimes for big commercial things. I think Nicola Tesla had some of his patents infringed upon.

Background on the Chinese wet markets and how they originate diseases:

I would answer - "In two weeks" :) We've started working on it. But Android is a bit ... emm... weird platform comparing to ios. So, it is unpredictable. I hope, we'll launch alpha version in 5-6 weeks.

Hi all! I am a CPL, SEL MEL and LSRM-A + ground instructor. Did a few tens of drops as a skydiving pilot. Also a software developer specializing in AI and biological-like systems. And my latest project is a part 103 ultralight based on drone technology to allow any A rated skydiver to self launch up to 10000 ft. Well the original prototype will be probably a hop'n pop at 3500 for someone 150 lb or lighter. The idea here is the skydiver will still "pilot" the craft through automation and even when freefalling. Already submitted a patent on the concept and using my skills as a light sport plane mechanic to create it. I hope to have something ready by next month. Needless to say I am also preparing a lot of explanations and reliability calculations and projection for the FAA but Part 103 i.e ultralights is fairly broad and probably the best way to get this thing going. And all the technological tools now exist minus the AI software I am creating to ensure quick realignment of the behavior in case of emergency and make sure the thing doesn't collide with the skydiver on the way back. Attach a few pics.... enjoy. And I believe skydivers are the lowest hanging fruit to get people in the air in the cheapest most minimalistic way. This is definitely uncharted territory and I want to give back to the community as I certainly fell in love with skydiving. Although I have fear of heights and will never skydive myself anytime soon Hope someone will want to try this for that matter. Not seeking to get rich but to revolutionize the field a little bit. Especially in the light of the deadly crashes in Hawaii and other places. Electric drive is a gazillion times more reliable than lawn mower engines, and there is 0 reason to not climb to a few thousand ft in a few minutes.
