The Bell Jet Pack is really a rocket engine powered by hydrogen peroxide, the same stuff in hydrogen peroxide 1/2% mouth wash and in the antiseptic form 3%. Hydrogen peroxide used for rocket fuel is at 90% strength or better. Since rocket engines are terribly inefficient, but powerful for their size, you will obtain less than 25 seconds of flight time with a Bell Rocket Belt. Production models now exist where you can own a functioning Rocket Belt for about 200,000 dollars, and that comes with training on how to fly it. True Jet Packs, ones made with turbine jet engines and not rocket engines, have a theoretical flight time of about a half hour. At a vertical flight speed of 90 miles an hour, a jet turbine powered Personnel Propulsion Unit as the original Bell Jet Pack was called would have a range of 45 miles before needing refueling. There are currently some prototypes of the turbine powered Personnel Propulsion Units flying. As a concept, the original Bell Personnel Propulsion Unit is very simple. Hydrogen peroxide liquid under high pressure is driven over some catalytic screens made from platinum metal. On contact with the platinum metal screening the hydrogen peroxide decomposes to very hot steam and oxygen to form a high pressure jet of steam through a rocket nozzle. On the original Bell Jet Pack, what is called the catalytic pack, the screens had to be rebuilt after each flight. I assume they did their best job to recover the highly valuable platinum metal. Some other metals that will break hydrogen peroxide on contact into Steam and Oxygen are Silver, Gold, Palladium, Rhodium. The most universal catalyst of all is Platinum which is the same stuff used in your catalytic converter on your automobile. Platinum is usually coated on the surface of glass beads in the catalytic converter, so if you ran hydrogen peroxide through your catalytic converter on your car you'd have the essential ingredients for a rocket belt, minus all the important control aspects of a machine that would actually sustain flight in a controlled fashion.
This was never known as the "Jet Pack"

The biggest pipedream in all of travel is taking to the air with a jet pack.
Since the 1950s, modern man has dreamed about strapping on some type of rocket to his back and jetting off to work or play. This was supposed to be the future of travel. Back in 1953 when the first jet pack was built by Bell Labs Aerospace, every ten-year old kid dreamed of the not-too-distant future, say... 1990 or 2000 when such an invention would be....

In the write-up, I did mean horizontal flight and not vertical flight. I'll have to re-edit this video at some point as I see the text is largely un-readable.
