Next generation of water jetpacks lets you fly and dive under the water, too. These guys make it look so easy...

    I don't think Iron Man was tethered to his jet ski and reaction mass source by a ~50 foot hose. It is a cool hack but not exactly breaking tech.

    The 2.5 liter, 385hp v6 jet skis they are using aren't too shabby either!!

    Really cool, but I have a feeling Darwin is really going to have fun with this.

    It seems counter intuitive but when the jets are at the base the unit is much more stable and easier to control than when at shoulder height.
    An example, there was the Hiller_VZ-1_Pawnee. This used simple weight transfer for relatively inexperienced pilots. The stability was largely due to the center of mass being higher than the reaction force location. Some have said it was as simple and intuitive to ride as the Segway. Which is really fun, just like riding a bicycle.

    As opposed to:
    The jetpacks are difficult to control as the controls are counter-intuitive. They take considerable training to master.

    While I'm to old and fat to do this stuff anymore I think the water jet platform would really be a hoot!!!

    The porpoising was actually pretty cool to watch.

    I suppose the Coast Guard could deploy these to deal with in harbor boat fires. But I can't seem to think of anything else they might be used for.

    The porpoising just might end with a rather severe headache at the end of the day.

    Extreme sports were meant to be watched, not participated in. Parkour being one of the better examples:

    My knees hurt watching that! At least it had listenable music though ;)

    Joyously bounding off to the orthopedic ward. Now I know what that bump on my roof is.

    Check this Rube Goldberg-ish contraption with integral human interaction.

    OK, that was cool! Can you imagine how much fun it was putting that together and rehearsing everything. THAT is engineering!!

    Actually, he was. You just have to look REALLY close, they used very thin fire hoses

    If you watch closely, he never lands with his legs strait. This would reduce the loads on the knees but requires more strength. (he's also good at extending the landing past the first impact)

    One or two of the clips also highlight David Belle's other master skill. That being the ability to f'up those moves and not get injured.

    The only problem is the fly is always watching their back from being whacked flat.

    Only with good medical coverage. I have the claim to fame of being the only kid to perform a one and a half flip seated on a bicycle.

    If you know anything about flips, the take off was rather easy. But the landing is difficult to negotiate. Anytime childhood friends meet up with me and have a few drinks in them, this topic comes up. At least, I have never broken an arm or a leg, but the neck is badly damaged.

    As with BASIC Stamp math, bicycle flips are only handled properly as whole integers. One is good. Two is good.

    One and a half is right out. Unanticipated truncation results.
