Perhaps one could make an auxiliary tank supported by helium balloons.

No, the $2.7B balloon that was supposed to be watching for that sort of thing broke itâs moorings and was last seen dry humping Ted Cruzâs legâŚ

So did he actually fly around the statue, or just around the statue?

Thatâs great, but why is the âTaste the Bushâ lady illustrating it? Something screwed in your html?
Heâs white.

Itâs impractical-seeming for casual use as transportation. For military, I can see some applications. Parachute out of a plane, then surgically place yourself in a precise location on a rooftop. Chase someone by car, then exit out of the sunroof, overtake who youâre chasing and unload a machine gun into their car. 5000 ground troops swarm in over water from ships at sea. Etc. There are uses. And some Hollywood uses.

Awesome. The only thing that would have made this even better would have been an F-18 shooting him down.
Water doesnât âpush backâ any more than air, or vacuum. Newtonâs second law is all you need: the mass of the propellant multiplied by how much you accelerate it out the nozzle is equal to the upward force of the engine no matter where it is.

No, hovering helicopters can take advantage of ground effect. Rockets can be seriously damaged by gas pressure between their engines and the ground. But a helicopter is going to get a lot more ground effect because of the large rotor disc.

weâve had this type of jetpack for a while, unfortunately they suffer from two major issues.
- difficult as hell to control
- inanely short flight times before they need to be refueled.
so for a lot of money you can fly very carefully with lots of training for a few minutes.

Youâd think we could cleverly beef up one of those tiny camera drones* to carry a person around in the stylish inspector gadget manner, but no. Damn you, physics.
*Yeah, I just call them drones. Deal with it.
The Flying Bedstead at least had an ejector seat, and even then it was described as insanely dangerous by the likes of Neil Armstrong. This jetpack works the same way, with downwards pointing gas turbines, but no ejector seat.
Itâs 2015. Donât we all know this by now?

Mayman prefers the term âmuch more manoeuvrableâ than rival designs.
