De Seversky noticed an air flow developing between the two electrodes, caused by the ionization process previously explained. So I began to develop the idea. The major seemed concerned that the Ionocraft might be mistaken for a kind of space vehicle. It's an airplane, designed to operate within the atmosphere. But it will be able to do things that no present type of aircraft can accomplish.
Helicopters whirl their blades in utter frustration at altitudes where the air gets thin.
Beyond 20,000 feet, they get almost no lift. The bigger it gets, the better it flies. Efficiency increases with grid area. Disturbing airflow around the grid edge becomes proportionately less important in larger craft. No practical speed limit has yet been determined.
