    ***She shot video in portrait-aspect, so I have no problem with people condemning her.



    What does portrait aspect mean?

    The long dimension of the screen is vertical, i.e. tall but not very wide.

    The other possibility is "landscape", which means the long axis is horizontal, i.e. more wide than tall.

    Computer printers use the same term for the orientation of a sheet of paper.

  5. Don't make your bar-tacks so wide that the thread skips back and forth over the entire line and stitches only on both sides of it. Make it narrow enough so that the stitches go through both the outer sheath into which it is fingertrapped, as well as the line which is finger-trapped inside.

    I ain't no rigger, so don't listen to me.

    ***Looked landable to me.



    This :)

    It's there. It's square. It's flying straight. The slider is up the lines about a foot - no big deal. And you can flare with rear risers. Heck, I wouldn't want to waste a reserve pack job on that.

    You're survey doesn't really have room so I'll elaborate further. Skydiving helmets suck fucking ass. The people building them are idiots. A helmet has to absorb the impact. It has to spread and dissipate the kinetic energy. Some of the might be able to do the first but they generally can not do the second. The shells are too heavy and they do not have enough room between the skull and the shell. Protecs are some of the better ones you'll see and they suck ass. They do not dissipate the energy. You get fucked up blunt force trauma injuries where the skull might be protected but the brain is damaged inside the skull. Bike helmets learned this lessen long ago. They use a thin crushable shell. Fractures like an egg shell. And a low density Styrofoam to absorb the energy. If you could do a mold that would be the right shape, non snag able, for a skydiving helmet and do a thin shell Styrofoam injected design you might be able to do it cheep enough to sell them by the truck load. People pay way too much thinking that it should last forever. It should be viewed as a replicable, disposable item. Any time it takes a good hit it should be ruined. And you should take that as the sign of a good helmet.



    And it has to look cool. Because if it doesn't look cool, then nobody's going to buy it.

    Was wondering if there has ever been a design where the brake line connected cells were split from the rest of the cells, on the trailing edge..... Something like an aileron on a plane wing, where the rest of the trailing edge would remain straight, and only the "control surface" would change during input.



    Good question. It does seem kind of odd that our parachutes are still inducing turns by warping the wing just like the Wright Brothers did it back in 1903. Seems like some better method would have come along since then. Maybe these split tails create more malfunctions by giving lines a crease in which to get stuck creating more line-overs?

  12. Complicated issue.

    Florida is getting crowded and many places are running out of land. Like the east coast from Miami to West Palm Beach. Everything between the ocean and the Everglades is pretty much already full.

    Land preservation is important. But at what cost, how much, and how to fund it?

    When I lived on the east coast we did something like this at the County level, voting to approve a half-cent sales tax increase, for the purpose of buying up beach-front property for public use. Vast stretches of beach are all privately owned, leaving the general public with no place to easily get to it. So the residents were all in favor of snatching up some land to preserve it for public access into the future, before it all got into private hands and off-limits.

    From my perspective, I think everything boils down to probabilities. What is more likely to happen? An additional problem because the RSL/MARD released the reserve in a ball of crap, or that somebody (that has disconnected the RSL/MARD due to the first scenario) for whatever reason lost altitude awareness and can't pull the reserve after a cutaway in time to save their ass?

    I don't have the answer, but I am under the impression that the second scenario is more likely, and therefore it has more importance. I also think that the "won't happen to me because I have lots of experience and I'm above the curve" attitude can eventually bite many people in the ass, as it has happen before many times.



    The probabilities that exist for a newer jumper are different from the probabilities that exist for a veteran jumper. Therefore, overall probabilities don't necessarily serve everyone's best interest. There are niches or other categories where there are interactions with different probabilities, and RSL probabilities shouldn't be taken as stand-alone, isolated from everything else.

  15. "So how do you get from down there on the ground to up here?"

    That long loop of cord hanging out the back of that guy's helmet looks like trouble waiting to happen.

    "First you have to hand pack your parachute…"

    Flat-packing is so out of style.

    "Your helmet is equipped with an altimeter that makes a shrill beeping noise when it is time to pull the cord."

    Last beep at 1800'? That's your hard deck. You need a warning BEFORE you get to your hard deck.

    Funny stuff!

  16. Not a doctor.

    But for a tandem passenger, this shouldn't be a problem. The passenger really doesn't do anything with their arms anyway, except hold on to their shoulder straps for exit, and spread your arms out in freefall. There isn't much force or strength involved in either of those.

    Steering the canopy is often allowed by the passenger, and requires some dexterity and strength, but that's strictly optional.

    He is arguing just to argue. This is why I rarely post on this sight anymore...



    "He is arguing just to argue. This is why I rarely post on this sight site anymore..."

    Nope. Just wondering how only certain categories of records got set in stone, to the exclusion of all others.

  19. Okay, so women need special record categories because they're a minority in the sport.

    And we already have gay records, because they're a minority too.

    And old farts, because they're a minority also, 40's, 60's, 70's.

    So why not African-American records? Aren't they the most stick-out-like-a-sore-thumb minority in the sport?

    What's the biggest freefall formation comprised entirely of African-Americans?

    Is there anyone that's NOT a minority? Yeah, young white males. Fuck them! :P

    ******Weight belt filled with water. Drain tube going down to the shoe.
    Dump the water after freefall, under canopy.
    Get the freefall speed you want without increasing the wingloading



    I was considering this until I looked up the density of lead (verses water).


    Mercury is heavier than lead and a liquid :)

    But on hot days it might swell up like a thermometer and explode! I'm sure there wouldn't be any health side-affects though, of getting it all over you.

    What's the best way to bring your speed back down to TV? I would assume belly, get flat and get big.



    Yep.

    Quote

    What is the effect on the body going from these high speeds back down to TV? Are there safety concerns about the process - i.e., can things go wrong?



    Not really. Even dramatic changes in speed like from a head-down speed dive at 250 mph to belly-flat at 120 mph, won't produced enough deceleration or drag to snap your arms off or anything. It feels kind of neat actually, experiencing that extra pressure.

    And you can make the transition gradually if you want instead of suddenly.

    ******Some people should go out and do it instead of whining.



    Some people should be able to debate a point without calling others with whom the disagree "whiners".

    I called it as I see it.

    Then again, some other people just like name-calling.

    >It's not a real "record" if many other people have done it before, and you're just
    >the first one to fill out paperwork on it.

    You can feel that way if you want. You could, for example, claim that the Australian or UK bigway records mean nothing because the World Team got a 400-way. Fortunately most people don't feel that way, and more skydivers have the opportunity to participate in local, state and country attempts before they (for example) try to get on a world record attempt.



    The context here is STATE records.
