    ***This one went to great lengths to get every detail wrong, and you just know the anti gun nuts will still be all hell yeah ban them all! :D:D:D



    Pssst... It's a parody.

    Heck, even most of the legitimate and serious anti-gun efforts seem like parody.

    ******I know Dr Karl, a famous Australian radio scientist wrote about this many years ago.
    Found a youtube video on it.

    That was actually pretty good. The closed-caption translation was a little rough, but close enough that you get the ideas.

    So why is it that our instructors always told us to tense up our leg muscles to brace for impact for a PLF landing? From this story, it looks like having relaxed muscles would be a better way to land and avoid injury...

    What you should have been told was to bend your knees and absorb the initial energy in your leg muscles as you continue through the PLF/R.

    Relaxing your legs too much will result in an injury.

    Right, but with your knees bent slightly, you tense your leg muscles in expectation of the impact. You don't just let your legs hang limp. Yet, this seems contrary to what they're saying these high-falling cats do.

  11. The thing they highlighted on the NPR radio show was this:

    Cats that fell 5 stories or less were rarely hurt.
    Cats that fell from 5 stories to 9 stories were often hurt.
    Cats that fell from over 9 stories, were rarely hurt.

    So why is it that the over-9 story falls had a low injury rate just like the much lower falls? It's the opposite of what you would expect.

    Before you go....could you get together with some of the others and ask the moderator to delete this thread and please delete my account?

    Some of the posts on this thread have already been removed or deleted, so I know it can me done. I have no option that I can find to delete this thread or my account.

    Seriously, please complain to the moderator and ask that I be removed from this forum.

    Thank you.



    You've received lots of helpful advice and information here. You just don't like it because it doesn't fit the conclusion you want to reach.

    You can remove yourself by just not coming back. Take charge of your own destiny. Cut-away from this thread.

  14. Well, before making such an important decision, one must do some research, right? So the porn star's name is Julia Boin, and you can do a google video search for "Chinese porn star Julia Boin" to find her body of work (pun intended). Then after watching her in action, you can judge responsibly whether or not a night with her would be worth giving up a Porsche. Strictly in the name of scientific research, of course. Julia does have interesting boobies...

    "I" was asked if I was under a reserve.

    I replied: "Is there an easy way to tell?"

    I was told, "if I was under a reserve, the toggles would be red".

    I then discovered that this information was not "entirely" accurate. And I posted an "amendment" to the above information that "not all reserve parachutes on tandem rigs have red toggles" And posted video proof. (google "reserve tandem ride", it's the first video that pops up btw)

    You are big boys. You jump from airplanes. Your wittle feelwings shouldn't be hurt so easily from "amendments" to your posts. Or for that matter, being shown you are wrong.



    Let it go, Willy. Walk away.

  16. Old story, but perhaps of interest here. Heard it on NPR radio today.

    On Landing Like a Cat: It Is a Fact

    EVERY year, scores of cats fall from open windows in New York City. From June 4 through Nov. 4, 1984, for instance, 132 such victims were admitted to the Animal Medical Center on 62d Street in Manhattan.

    Most of the cats landed on concrete. Most survived. Experts believe they were able to do so because of the laws of physics, superior balance and what might be called the flying-squirrel tactic.

    In a study for the medical center, Dr. Wayne Whitney and Dr. Cheryl Mehlhaff recorded the distance of the fall for 129 of the 132 cats. The falls ranged from 2 to 32 stories.

    Even more surprising, the longer the fall, the greater the chance of survival. Only one of 22 cats that plunged from above 7 stories died, and there was only one fracture among the 13 that fell more than 9 stories.

    Why did cats from higher floors fare better than those on lower ones?

    One explanation is that the speed of the fall does not increase beyond a certain point. This point, ''terminal velocity,'' is reached relatively quickly in the case of cats. Terminal velocity for a cat is 60 miles per hour.

    Until a cat reaches terminal velocity, the two speculated, the cat reacts to acceleration by reflexively extending its legs, making it more prone to injury. But after terminal velocity is reached, they said, the cat might relax and stretch its legs out like a flying squirrel, increasing air resistance and helping to distribute the impact more evenly.

    Tried to find the paper in the medical journal, but their online offerings don't go back that far.

    Stable (cause he wasn't)
    Sugar Britches
    Axel
    Bookworm
    Comet (as he passed the formation)



    All right, ladies and gentlemen. Some of these nicknames are obvious and require no further explanation. But others like "Axel" and "Bookworm" do not seem to have any relationship to skydiving. Those kind require that you provide the story behind them, so that we can understand and be entertained. Thank you.

    Oh, and about "Sugar Britches": because they were sweet?

    I've just ordered a new rig and I'm curious. How long did it take for your rig to be delivered after you ordered it? Please list the manufacturer and model as well as the year you got it.
    Thanks!



    Manufacturers vary. Delivery times can vary by time of year, shortages of supply, and many other reasons.

    What did they promise you?

    Who is the manufacturer of your rig - you didn't even give us that basic info...

    "Mark the Narc"
    "Crazy Ed" (there are many Crazy Ed's in the world.
    "Ganja" (because his last name was Weed)
    "Maplehart," or "Dougie Maplehart" (neither was related to his real name)
    "Wragg" because when your last name is "Wragg" you have an automatic skydiving nickname



    Need the back-story behind "Mapleheart".
