Where is the centre of gravity? It had better be bloody low.

This is from the people with the previous water-jet version. The CG is low and the thrust is at the flyer's feet, but there are people who can fly the thing very well. Here's Gemma Weston, the 2016 champion, flying the water-jet version. If you have the thrust, it's possible to control the thing.

The videos of the Flyboard Air do look kind of suspicious. But it's not impossible to get the necessary thrust. Here's the biggest model aircraft jet engine, the B300F from BF Turbines. 390mm long, 133mm diameter, 2.5Kg mass, 300Nt max thrust, price about EUR5500.  Four of those could lift 268 pounds. They're not rated for human flight, but at least you have some redundancy if an engine fails.

A thrilling sight. Human flight! But as I understand it, rocket-packs or jet-packs or other devices for shooting a person up into the sky always have had the potential to work, if dangerously, but never for more than 13 minutes. This board lasted 4 minutes. If this is true, the flying ex-pedestrian will never darken our skies.
