Skyper

he won´t even need to pull

head down openings can be very hard... and mysterious

it would be more in the Russian tradition to jump with a bear in tandem

there is one more person on dz.com described similar scenario happend on a tandem jump whereby fast release of the brakes solved line over...

IMHO this is for the section "marketing".

"every time" is hard word in this forum... however you can reduce the chance of packing tension knots by keeping the lines tightly streched during the entire process of packing. don't try to "iron" them by pulling them from the middle and than up. As someone said previously it's also a good idea to untwist the steering lines from time to time. Relax. You are overthinking the entire skydiving experience. Just relax and listen to you instructor - he'll tell you everything you need to know and don't overload yourslef with that kind of material prior your first jumps.

what kind of rig (deployment mechanism - SL, throw away, ripcord) was that? What kind of jump - AFF, static line...?

do you have such hard openings only on Safire or did you have it also on other canopies?

why don't you reserve some time to sit beside the packer (you apparently trust) and see how he is doing the packjob? those guys are usually friendly and willing to show you their way. Than try it for yourself...

Oh yeah, like anybody's ever done that. Um, some of us do/did. how many DZ did you visited before you decided where to take your first course?

and thought that you were saying that the worst case in SL is a premature, but re-reading I guess you didn't mean that. ohh, I c. I think the sentence was too long. Indeed, in some cases SL can be very nasty as well.

What do you actually want to say by posting this video?

Not completely, but it seems to be getting better gradually. Basically I just have a little crackling when I open my jaw or swallow. I'll probably give it a few more days, hopefully it'll be cleared by then. Never had sinus trouble before. if you cannot clear don´t jump. if you have pain don´t jump. Ascending is not such a big problem but falling might be. While under canopy - swallow often. Once on the ground clear your ears. If you cannot clear - don´t jump any further.

are u able to clear the ears?

Bill, thanks for explanation. There is important difference between SL and this "method". SL is not connected to canopy but only to pin and free bag. Which means that any snag of the static line to any part of the plane or any part of instructor in the worst case may result in a bit premature opening of the main - and indeed nothing happens. However in IAD... PC and bridle are connected to main canopy - if PC or bridle snag to any part of the plane means that the part of the canopy remains connected to plane or to instructor and this is a different situation than SL snag. This may result in premature opening on the door and snag of the PC, bridle or other part of the canopy to the plane. Therefore I think this method induces more risks than SL.

Yup, that's IAD. It's a way of training new jumpers, like staticline but without the need for static line gear. I wouldn't like to imagine what would happend if... - the student slips by accident on while climbing out - the bridle snags on some part of the plane - the bridle/pc snags on the instructors arm or part of his equipment - the student goes a bit too fast to the door and pulls the pin - the instructor remains a bit longer behind the student and pulls the pin imho, way too much risk

in my time PLF was mandatory because of the round canopies and significant vertical speed. once i switched to square canopy I was surprised of how soft the lendings can be... by saying that square canopies give far less opportunity (or urge) to train PLF's... and probably is that the reason ppl got injured on the jumps where a simple soft PLF would save their health... the solution? I don't know really. Youngsters of the present day put the thrill too far above safety. It's social and not skydiving issue. edit: Appearance is becoming more important than safety. Rolling is kind of inferior to standing position... not to mention the possible teasing you might get because of your dirty jump suit... :D maybe it´s better to stay vertical and clean even with some medical record than being dirty from rolling in the dust.

when it comes to insurance claims, insurance companies will certainly be able to do something about it... What? I'm unsure what you are claiming? imagine a situation where camera was identified as a main cause of fatal accident of the person not entitled to use the camera during jump - whatever size of that camera might be. IMHO, life insurance will not grant the payment if they discover there were irregularities in the usage of the equipment like the situation above.

How do you come to that one?

Is this situation, is the the updraft thermal like a steady current? I wasn't completely confident about the shape of a thermal, as to whether it was like a column or a bubble. If it was like a bubble, though, would it be possible that while the jumper is mid-deployment and the canopy is sniveling, he could pass through a bubble traveling upward, thus speeding the opening of the canopy? I assume this is highly improbable, but I thought it was an interesting situation. except if you are in the middle of a thunderstorm the speeds of vertical winds in turbulent weather conditions are very very low and do not influence the opening sequence in significant way. What we experience as "turbulence" under canopy is the difference of only few kilometers per hour in the vertical wind speed.

in theory, when object is falling and the wind is blowing vertically into that object... wind will only reduce the objects vertical absolute speed. In theory this kind of wind will slow you down and your relative speed will remain unchanged. in practice the influence of vertical current on opening sequence is not significant. but of course it may influence what is happening after the opening... since you're going from falling into the gliding mode. your body position is the variable that influence your falling speed and your opening sequence in the most profound way.

It's true. I have two tunnels within 2 hours drive from my home. Maybe is that the reason that I thought that it's "widely available" thing. I thought that this kind of tunnels are all over US, but I was not aware of the large distances you have to make to reach one. I hope for the good of everyone involved in this sport the tunnels will be more and more availabe in the future...

it is very easy to check whether your claim is true or not... the highest humidity region is usually within and around a cloud. The relative humidity is there nearly 100%. Next time you jump in the cloudy weather open within the cloud and check for yourself. Please post your findings inhere. edit: humid air is indeed less dense than dry air. This means that the terminal speed through humid air is higher than terminal speed through dry air. If higher terminal speed leads to harder opening than this story does make some sense. But I don't believe that humidity may influence terminal speed more than a temperature changes. In other words: do you have harder openings in the summer? If the answer is NO, than the influence of humidity on intensity of the opening is not significant as well.
