The jet pack, which in the late Sixties was what we were told we'd all be using to get around ca. 2000, was powered by high strength hydrogen peroxide. Aside from the volatile (and thus dangerous) fuel, a major drawback was that the backpack sized units only carried enough fuel for thirty seconds or so of flight.

For demonstrations, such as at football games, the pilot would fuel-up in the parking lot and fly up over the stands and land on the playing field. Longer filmed sequences of guys jet packing over the countryside were painstakingly edited together from many separate flights.
