In the published video, we can see an object that resembles a man with a jetpack. Several companies in the world are working on such inventions and even use them often, but this time the object was moving quite fast and the flight took place at an altitude of about 1500 meters.
Richard Browning, the head of Gravity Industries, often uses his jetpack and presents his flights on YouTube, but before that the whole project is well thought out and planned, and the relevant services are informed about everything. Meanwhile, in this case, the flight took place without permission and without respecting the safety rules.
In the film, we can see flight at great speed and at high altitude. Flights in jetpacks are carried out at an altitude of several dozen or several hundred meters, not thousands of meters. If there was a hardware failure, and it does happen frequently, the jetpack operator would have no chance of survival, so we're really talking about playing with death.
There have been several incidents with such facilities recently. During one of them, probably a man with a jetpack approached the passenger plane only 270 meters. The pilots considered that he posed a huge threat to them and the passengers of the plane. The FBI is dealing with cases, trying to find out who is organizing these flights.
