    Extra cool points to be awarded if he still had the cutaway handle in hand.



    The loose cable will beat you in the face (or so I heard.) :P

    For a mister bill:

    How about if Mr. Bill turns 180 degrees haf a twist on risers. This way the sluggo will be travelling face forward and may toss the PC. In case Mr. Bill has a slow canopy, just add some rotation and things should take off from there ;)

    All these people crying about weak plots must not watch any porn either for the same reason!



    Good porn goes straight to the action. Poor erotic movies have poor acting, poor plot and poor action.

    As said earlier, you can find great wingsuit flying on youtube without the other crap.

  7. As far as I remember, there have always been those people who say look up or look down. They couldnt be more wrong. The truth is that you should always try to keep your spine straight and look to the horizon. Anything else will cause you injuries.

    It's actually quite easy if you think about it. Try to put your chin to your chest and push your head down with your hand. You will quickly notice you cannot really put much pressure on your head before it starts hurting. Now put your spine straight and look to the horizon. You can actually load a lot of weight on top of your head as long as you keep your spine straight. 20 kilos is nothing really. In many cultures, people carry heavy loads on top of their head when doing manual labor. They most definetly keep their spine straight. The same goes with just about everything else also: deadlift, squat etc. You name it. Your spine cannot take much punishment when it is in bent orientation.

    I have seen some old school guys build handles on the sides of their helmet. Their strategy was to hold those handles while they took the opening shock. This in addition to keeping the neck straight is one option if jumping heavy equipment. However, these guys were jumping more than 10kg on their head. 2 videos 2 SLR´s plus flashes and battery packs.

    I always felt canopy choice is very important when jumping an SLR. Actually Im convinced I would have no problem jumping 2x SLR´s with flashes as long as Im jumping something like the Crossfire2.

  9. This was discussed 3 years ago. It seemed that those who had experience on putting go pros to students were totally ok with it. Those who did not have experience over this, opposed the idea strongly.

    Common sense would suggest it is safer to have the student wear the camera than the TI. This way TI can focus better on doing their job. Most likely the quality of the footage is worse, but I would guess in some ways it makes the video even more personal to the tandem pax, since they get to film the jump by themselves.

    And other adults are free to tell them to put it on, since the result of not saying anything could well be death. (Also, many DZ's do require your rig to be on and jumpable before takeoff, in case of an emergency exit or a PC out the door.)



    The main issue in this case was the unwritten hierarchy in skydiving – not the chest strap.

    Someone wanted to state his superior position and the other one didn't want to concur. The chest strap was irrelevant.

    No idea how it is exactly where you're at-but I have seen this same issue here in the States... Had some "angle flyers"/tunnel rats get pissy with me because I asked a guy on the plane during taxi to thread his chest strap. His buddy looked at me, said: "He's leading our jump, I think he knows how to put his F@$&ing chest strap on!" My response was "cool, show me".



    I wouldn't have liked your attitude either. It's good to make sure the person is aware he has an open chest strap, but another to command one to fasten it.

    In fact I think you were positioning yourself on a high horse as you started to dictate how others should use their gear.

    Personally I always thread my chest strap before boarding, but other adults are free to choose themselves imo.

    ***Just wanted to say that 65 euros a month for this sort of insurance is far from cheap. The insurance company is basically printing money.

    last time I bought one in Spain, it was around 30€ a month.

    In Switzerland we have a temporary one for CHF54 for 3 months

    In Finland we get the third party liability insurance (up to 1.000.000€) and some sort of accident health/life insurance (up to 10.000€) as a part of the FAA membership.

    FAA membership costs around 70€/year and I would estimate that the proportion that goes to the insurance company is no more than 10€ per member.

    I would suppose even then the insurance company is making good profit.

    30€ a month for a 3rd party liability insurance is at least 40 times more expensive. If its 65€ a month is ridicilous.

    EDIT: BTW. Have you ever heard of anyone who has covered some kind of liability from such an insurance?

    Third party liability insurance is available for relatively cheap (~65 euro) and can be arranged in an hour or so while at the DZ. It lasts a month, so for anyone in the future this may be a great option if you're bouncing around a bit.

  18. Thats a cool stunt, but a bit different one. In the pictures there are supposedly two CReW fliers and the otherone takes over the other CReW fliers canopy. Also he does not land with one canopy but two canopies.

    EDIT: I remember seeing a video where two guys land a mr. bill with the other guy sitting on the other guys shoulders. I think it was shot at WFFC perhaps late 90s.

    If you turn hard enough to get your body above the canopy in theory you should increase your vertical speed because your lift vector is now pointing at the ground. The vertical speed obviously will translate into forward speed. Personally I think this is where a reversal works in your favor. To me it just seems easier to really turn hard in a reversal.



    Interesting stuff. Your point about the lift vector makes sense if you ment to say that the lift vector in this case is pointing horisontally in a slightly downward angle. (not towards the ground)

    However, I wouldnt agree this could be better utilized with the reversal technique. On the contrary, I would suppose the reversal technique makes you loose this optimal pilot-canopy orientation for a brief moment once you make the change in direction.

    My gut feeling would say that the techniques mentioned in this thread earlier – turning on a spiral that goes tighter at the end – would be the most likely to 1) keep you slightly above the canopy 2) transalate the centrifugal force into a faster downward speed through the slightly downward angled lift vector. -> so the faster your turnrate eventually builds up, the more you can utilize this downward lift vector.

    Im no way near a competitive swooper, but in theory I understand "the extra snap" you get when your last turn is rather fast and you hit it well enough. Perhaps this is where it comes from.

  23. Unless you know skydiving, its hard to explaning exactly how serious it was. Its not like we can just hand you any percentages of survival. Even experienced skydivers propably see this sort of situation a bit differently, but all would agree that it is a situation that could potentially end up the worst way. It is quite rare, and the tandem master will definetly remember that jump the rest of his life.

    The dropzone definetly wouldnt like to have this sort of photos circulating around the internet, so obviously they couldnt let you have them.

    Glad it turned out good.

    OK, I'll bite. Explain why you are bulletproof from a premie?



    No one is "bulletproof". We just seem to have a very different view on how likely this scenario is. There are many things that add risk to a tandem skydive. One example is hand cam. It definetly does add some risk, but most of us nowadays see the level of risk being acceptable.

    Now where things get interesting is when someone would give the handcam to the customer. There are many of us that think this would actually be the safer way to operate opposed to the TM using the hand cam. Then again, there are those conservative TM´s that refuse to accept this idea. They think the student has no bisnes operating a hand cam.

    This is a perfect example in demonstrating how differently people asses different risks involved in the sport. There are many things that get overlooked in our sport, and there are things that get make people paranoid. Often the logic behind it is not based on a rational risk assesment analysis.
