Why didn't the FAA get the cops or military to scramble some jets to apprehend this individual? How is this not a national security threat?? Who knows if they were strapped with IED type device.

Wow - so he can - here's a video https://youtu.be/lK75XLUIKUk?t=8

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.

Those turbine-powered models aren't carrying 100+ kg of payload?
These rc model turbines pull 20+ kg thrust. In the video he uses turbines noticeably larger, in 50-60kg class. Granted such small turbines have low efficiency - low compression - so they burn 0.2kg fuel per 10 kg thrust per minute. Thus 4kg per minute for 200kg total weight of which fuel is 60kg at best, thus 15 minutes hover at best. Once it becomes more popular we'll get turbofans, and that will improve the efficie…

From another viewpoint: people fly turbine-powered model aircraft all the time. Why wouldn't you believe it?
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.

Glassdoor says they earn $30k - $64k yet lots of us earn more in our comfy office jobs typing code into a text editor, kinda puts things into perspective.
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...
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 with the following, discussed on HN twice in the last day:

We found truck drivers loaded up with $262,898; city painters making $270,190; firefighters earning $316,306; and plumbing supervisors cleaning up $348,291 every year. One deputy sheriff earned $574,595 last year – including $315,896 in overtime
All paid for by tax dollars.

That is a friend of mine's site. If you live near an airport and have a good internet connection volunteer to provide a live feed.
I live close to LAX. I'll send them a message.
Don't get me wrong! I'm not trying to demotivate you. Just letting you know that maybe they'll turn you down. However, even if they do so, you can always learn a lot by doing so... and it's quite cheap, and redundancy is always welcome, right? :)

The FAA should still have a stern talking to the guy, of course, if he flew in the path of airplanes.

Anecdote time: I was in a train that hit a bunch of concrete slabs at medium speed (60 km/h?) and all I noticed was that it rapidly stopped. But that was a relatively undetermined attack. What if someone welds something directly on to the rails or cuts something out? It may get noticed in tens of minutes, but is that really fast enough? Similarly it seems like it wouldn't be insanely hard to poison water supplies, do…
Cutting out the rail is unlikely to cause huge damage, and welding something directly to the rail would take quite some time and be noticeable. Just putting a few sensors every few meters and networking them then stopping the train would work. But I am also surprised how well it works. I think people just don't suck as much as one would expect.
The US has a total length of about 300 000km of railway network and that probably counts multi-track connections once. And it doesn’t include subway or anything. So that would be a lot of sensors that need to be placed and maintained. And you’d need to except some failure of sensors, so you cannot just stop if a single sensor goes haywire.
It’s certainly not impossible, but also not trivially done.

How heavy of a battery would you need to power these with enough electricity to lift an adult human, think like a drone on steroids...

Looks like the motor you need. 25KW
ATCs have a reputation for never losing their cool and that really shines through here: “Tower, there’s a guy in a jetpack flying outside.” “Copy. To your left or your right?”
I listened to the audio book of “The Only Plane in the Sky” (do recommend), and they played real recordings of ATCs on 9/11 as the planes were hitting buildings. It was surreal listening to them talk about the catastrophe but all while maintaining a total sense of calm.
