  3. I agree that body position and folding play important role. But I just cannot believe that those two (particular) canopies I used can ever open softly without significant modifications. Hard (ening f. up ;) from time to time is okay but hard openings as default mode of a canopy is simply not acceptable for me.

    How did you deal with yours?



    sabre1 - 190. first jump, master rigger packed. HARD opening. second jump, DZ packer packed. HARD opening. third jump, I packed with all advices I got for soft openings. HARD opening.

    sabre2 - 150. first jump. A friend of mine packed it for himself. Not as hard as sabre 1 but pretty hard opening. I'm convinced that I'll never jump sabre again except if my life really rely upon it. :)

    I pull my cellphone out, video it, upload the vid on youtube, post it on my Facebook profile to make it viral... and then file a complain to the FAA in order to make medical checks more difficult.



    I don't think that would be possible. Cell phone umts network can in extreme cases reach 1000m (3000ft). In most cases the network signal is non existant above 300m (1000ft).

    But yes, statistics are when driven by a political agenda and therefore are bullshit.



    If unbiased, and proper and consistent data collection and criteria used, statistics can be very useful.



    some time ago I came across the statistical report regarding the fatal skydiving accidents in US. I cannot find it now, but what I can recall was:

    Chance of fatal accident per 1000 particpants:
    Motorbike driving 0,2% per year
    Skydiving 1,1% per year

    IMHO, one of the flaws of that report was the fact that they've calculated all registered motorbike drivers and not only the active population of them.

  17. there was a "Myth Bastards" episode on NatGeo channel. They tried to land the Boeing 747 only by following the instructions from the ground. Of course they did this on the training model on the ground and both tries were successfull. I've also read in the news some times ago that one old lady landed some small aircraft after her husband had a hart attack during the flight. She had some previous flight experience however and was guided from the ground.

    But anywayz, I would consider consuming the pilot, prior the bail out :D

  19. Skydiverek, following this research earplugs rated class 3 and higher would be enough for 10 jumps a day. The intensity of sound is very high (up to 115dB), but the duration is very short.

    I've been looking for the values for that "class 3 rating" and it appears that it is about 19dB (only).

    26dB damping, (which is very close to class 5 rating) would be more than enough, at least following the research results mentioned above.

    33dB is usually worn if you work in very noisy environment (above 100dB) 8 hours per day... :)

  20. Skydiverek, i use the ones with average of 33dB damping. But, there is one important detail: earplugs must fit well. In other words, if ear plugs are not custom made or made of very soft material which fits well it's damping power is lower than it should be.

    I consider now buying the custom made (very expensive) ones.

  21. An interesting research about noise levels and noise protection in skydiving:

    Quote


    Skydivers who wear hearing protection (rated class 3 or stronger) are less likely to receive a noise dose higher than 9.73% per skydive and would not exceed his or her noise dose if skydiving 10 times or less within an 8 hour time frame. Alternatively, skydivers who do not wear hearing protection (or hearing protection rated weaker than class 3) are more likely to receive a noise dose higher than 9.73% per skydive and would exceed his or her noise dose if skydiving 11 times or more within an 8 hour time frame.

    Hey everyone! Well, this is my first post and all. I am going to be a new student at the local AFF school in one month. Skydiving is something I've always wanted to do. My questions is this, do most students do at least one tandem before they do AFF school? And those that have done a tandem jump, on average do better than those who haven't? In your opinions, should a student buy some gear to use during and after their school such as an altimeter, helmet and goggles? Or do most schools/instructors advise not to buy your own gear because the school wants students to use their gear? Thanks for the responses!



    Save your time and money by avoiding tandem. If you want some experience prior your first jump - take 10-15 minutes of the tunnel time for the same money of only 1 tandem jump. The first 15min of the tunnel time will be worth every penny of it. Regarding the gear - buy only the googles that fit well on your face and buy the clear ones so that instructor can see your eyes during the free fall. You don't know yet if you ll really like skydiving or not, so rent that basic gear for your AFF jumps and if you want to have more... buy your own.
