    P.S. Theres gotta be a video of some sort of a military G Force deceleration test that can prove how -2g looks like...
    Its similar to blacking out when you do positive G, expect that instead of seeing black, you're vision goes red. It also hurts really bad, like your head is going to explode - think of a migraine but on steroids.

    It's better to not pass and know that you could have than to pass and find out that you can't. Wait for the straight.

    I've watched a lot of space and spaceflight documentaries over the years. In one of them Chuck Yeager volunteers to test either ejection seats or mockup of the first Mach 1 plus aircraft. Cant remember which. He got about (IIRC) plus 6 G accellerating and -3 or 4 decel. (wired up like a christmas tree). Major damage was the mini blackout from accel and burst bloodvessels from decel.

    I think they adapted those "grip your extremities" flightsuits as a result.

    More G than we're talking about here though.

    and no one has claimed the money yet.

    When they are discussing negative Gs in this manner they mean negative - vertical Gs. What you experience during acceleration or braking on a motorcycle or in a car/plane/etc are lateral Gs. You are much more resistant to lateral forces than vertical forces - mainly due to how your blood vessels are laid out.

    This is also why astronauts are lying on their backs facing the direction of travel of their spacecraft.

    When it comes to vertical Gs fighterpilots use a combination of muscle-tensioning techniques and their G-suit to prevent the blood from draining from their head during high positive G maneuvers. However, neither of that helps very much against the negative Gs since you got no muscles in your brain that you can use to squeeze the blood out and neither does a helmet do much for you in this regard.

    Yeah, talk about balls being the first man ever to test a prototype for a supersonic ejection seat

    There was one guy who was subjected to a braking force of 15g on that crazy rocketsled of theirs. He was in a poor shape afterwards, but recovered perfectly. One injury he sustain in being subjected to these forces was that his retina delaminated from the back of his eyeballs - crazy shit. At least it grew back together.

    I was trying to work out how fast 'ol skiddy had to stop in order to make his 2 meters claim.

    60km =
    60000 m per hour =
    1000m per min =
    16m per second.

    So Skidmark had to stop in 0.125 seconds for his two meter claim.

    I'd bet his pocket isn't willing to back up his (pruddy) mouth.

    I agree, this would be a good acid test.
