Paul Sizz was one of the world leading experts in hypersonics and air-breathing magneto-hydrodynamics propulsion.

Plasma sheaths are used to reduce drag and stress on hypersonic aircraft by modifying the flow field.

The Russian Ajax project that the United States was developing was converting traditional ramjet scramjet engines into heat exchange systems using electromagnetism.

The technologies used include MHD generators neutron beams MHD accelerators and cold plasma beams to modify the flow field.

The virtual aircraft approach changes the environment around the aircraft rather than designing the aircraft to withstand high-speed flight.

The force-free toroid concept from 1967 is directly connected to Jack Nachamkin force-free time-harmonic plasmoids from the 1990s.

Once an object is covered by plasma and operates as drone without internal operators it can become much smaller and move 360 degrees in any direction.
