On the roof of the 45-story hotel Four Seasons Hotel in Denver, Colorado (USA), were tested new jet-pack, working on the basis of hydrogen and nitrogen. 30-second flight and soft landing (thus without any insurance) held a real daredevil and modern rocketeer named Nick Macomber. He made a small circle and landed safely back to the roof of the hotel.
It should be noted that the flight is part of a test preparation company Goal-fast to try to install a world record by flying from the roof of the tallest building, located in the southern hemisphere. This will draw jetpack fueled by compressed non-flammable mixture of hydrogen peroxide and nitrogen, which will create the necessary thrust for flight.
By the way, according to Western sources, one New Zealand company is currently working on the creation of commercially available jetpack and even got a license to conduct flight tests involving humans.
