From another viewpoint: people fly turbine-powered model aircraft all the time. Why wouldn't you believe it?
Those turbine-powered models aren't carrying 100+ kg of payload?

four of them so about 158 kg thrust total? It's impressive how well they work for what seems quite a simple and relatively inexpensive device.

Lift for how long? https://www.tmotoruavdrone.com/product-detail/48968207323300... Looks like the motor you need. 25KW
And you'd need four of those, I'd guess... so 100kW or so.
As amusing as this is, it highlights how fragile air travel is -- someone managed to fly a 200 lb payload within a couple hundred feet of an airliner on final approach. And apparently did so anonymously since there was no mention of who or exactly what it was. It wouldn't be hard to maneuver it right in front of the airliner and cause a collision. While the aircraft would likely survive an engine strike, at only a fe…
Yup. Air Travel is very fragile. That is why I never understand people who back flying car projects.

There's probably recordings publicly available somewhere, but I thought the same thing when listening to the Columbia disaster. It was the first space disaster play out in real time over the internet. NASA streamed mission control communication on their site. We got everything unfiltered. The nation just lost a pride and joy, and mission control was incredibly calm and professional throughout. I was constantly hittin…
I keep remembering hearing Capcom keep saying "COLUMBIA HOUSTON,UHF COMM CHECK OVER" You could just tell every time he repeated that it just got harder and harder for him to say it with out cracking.

It's amazing how much leverage an employer has when they have the legal right to simply fire everyone, and there is no recourse for the employees because the employer is the federal government itself. https://www.politico.com/story/2017/08/05/reagan-fires-11-00...
For people who won't click, here are some salient facts: this air traffic controller strike occurred in 1981 In 1955, Congress had made such strikes punishable by fines or a one-year jail term a law the U.S. Supreme Court upheld in 1971 You don't like it? Then don't take the job. Take a job where you do have the ability to go out on strike. When you simply cater to union-protected municipal employees, you wind up wit…
Those pampered government employees up here with their unions and pensions and benefits. It's awful. All they do is make our country work. If only we could get rid of them all and let private enterprise take over.
Think of how much better our country would be if we scrapped public transit and let Uber and Lyft take over everything.
Likewise, we could get rid of our ridiculously terrible public health care and adopt a sane model where the market provides. After all, markets mean efficiencies, that's why Americans pay less for healthcare, and get better outcomes than socialist hell-holes like Canada and Germany and the Nordics.
If taxation is theft, we should not only be able to fire people who are paid with our taxes, we should be able to jail them as accessories to the crime, and make them stay there until they pay back every ill-gotten cent.
I have spoken.

Well for one, where is the fuel? Seems like it would take a tremendous amount of fuel and there are no visible fuel tanks on the jetpack.
Edit: It appears that I confused Vince Reffet with another "jetpack guy" - Richard Browning. The number was for Browning's device. But although you could get more airtime by adding wings, the overall point still stands - the flights are relatively short.

Maybe, if they're that bored. But their transmissions won't be heard by the bug smashers down below.
They will if the pilot presses the appropriate TX selector button.

I did. www.jetman.com has more infos But nothing on the actual jetpack, like how the engine works. But here they actually fly next to a jet. So maybe it was those guys. https://www.youtube.com/watch?v=_VPvKl6ezyc&feature=emb_rel_...

I mean, you're supposed to, and you'll get in trouble if you're caught driving without valid insurance. However, there isn't anything physically stopping people from driving irresponsibly.
