209 green fireball/orb sightings near Sandia New Mexico 1948-1950. Copper powder residue found as physical trace evidence. 116 pages of investigations released via PURSUE Release 2. Green fireballs ap

Greek engineer starts E-layer field reversal concept. Earliest compact torus conception. Presented at 1958 Geneva.

Winston H. Bostick publishes 'Experimental Study of Ionized Matter Projected across a Magnetic Field' in Physical Review, coining the term 'plasmoid' for self-contained plasma-magnetic entities.

U.S. high-altitude nuclear tests provide empirical data on high-beta plasma stability and diamagnetic cavity formation in the Earth's magnetic field.

The Astron experiment established the field-reversed configuration geometry that prefigured modern FRC research.

H. Alfven and colleagues publish the technique for magnetized co-axial plasma sources, which later forms the basis for the CTX experiment.

December 1960 Radio-Electronics magazine publishes 'Ball Lightning for Defense?' stating: 'Electronic fireballs of highly concentrated charged particles (plasma) might be used to destroy missiles... T

A 1.4-megaton detonation at 400km altitude creates a massive high-beta plasma fireball, demonstrating stable macroscopic plasma structures on a geophysical scale.

Project ORION is terminated primarily for political reasons, ending early research into external pulsed plasma propulsion despite promising technical results.

Early declassified work on magnetized plasma shields for aerospace vehicles.
