USAF Project 1794: Declassified 1950s Flying Saucer:
…and WEAV — the Wingless Electromagnetic Air Vehicle — a prototype craft utilising atmospheric plasma propulsion that NASA is toying with now.
…using a plasma field you could produce lift in any direction, you could change direction quickly and that power could be turned on or off almost instantly…
This is fascinating stuff. I am looking into this magneto-electro-hydrodynamics tech for Book 3. I am looking forward to a real flying saucer!
