    I wonder how long it will be before RedBull gets involved...

    Kind of hard to see from a safe distance.

    These guys and Yves Rossy need to combine forces. Foot launch flying jet pack-wing.

    I can’t imagine a safe distance would be that much, if things go wrong these guys are more or less just on a ballistic trajectory to the water below. That and with the number of camera drones that would zip around an event like this I’m sure watching wouldn’t be an issue.

    I wonder how you would transition from vertical to horizontal flight. Huge spoilers? Fold the wings up?

    In 3... 2... 1...

    More seriously, how is it that these guys are not absolutely dripping in military contracts?

    Vertical climb until the airspeed over the wings is larger than the stall speed, followed by a pitch-over to horizontal flight. For the reverse, pull up into vertical flight, let speed bleed off to zero, then back down. All of this is the same as the old "tail sitter" VTOL aircraft. It's just that, since the pilot is standing in vertical flight, he'll have a much easier time judging the landing.

    I'm absolutely amazed someone hasn't bolted Rossy-style wings (with three-axis controls) to a jet-pack similar to the one in these videos. It seems like such a natural solution.

    Maybe when they stop having to fly over water it might say something. Seems like the crash rate is high since they only fly over water. Same with all the multicopter style platforms. No safety net.

    I remember a discussion on here, some time ago, as to whether these jet pack videos were real.

    They are real enough. And here is another:- https://gravity.co/ There is also a version that you stand on.

    ...maybe they are.

    But I suspect the problem is they have a very short range and make an awful lot of noise.

    The U.S. Army gave up on jet packs, right after they finally had one that worked.

    The https://en.m.wikipedia.org/wiki/Williams_X-Jet WASP finally let them test the concept, and while it gave awesome scouting capabilities, it was also so loud that it was useless in that role.

    Pity. I want one. If you are not worried about people shooting at you while you try and sneak up on them in the flying whistle, it's a great commuter machine. :)

    These being turbofan powered, I suspect they have "better" range than the older jet-pack designs, but yeah, since the most-likely role would be "covert", the noise is probably the issue.
