United States Air Force F-4 Phantom II aircraft bomb targets during a military exercise

Ground views of two F-4 Phantom II aircraft of the United States Air Forces in Europe (USAFE) participating in NATO military exercises. The Phantoms drop bombs on a target, evenly spacing the bombs along a long, narrow path. Explosions rise from each target site. From a lower altitude, a Phantom releases a group of bombs on a ground target, effectively destroying a larger area. Two Phantoms fly close together and then diverge in the air. Aerial view of a F-4D Phantom flying and rolling left.

Space research about the ionosphere from the ground by the National Bureau of Standards.

Film entitled 'Scatter Radar', from The National Bureau of Standards, United States Department of Commerce. Depicts space research from the ground. The globe rotating. A satellite antenna moves into position. Radio instruments. Red optical instruments used to study the sun. Clouds in the upper atmosphere. Animation: Ionosphere reflects radio waves to the planet. A smoke of cloud rises during the launching of a rocket. An artists' conception of the Van Allen Radiation Belt above the Earth's ionosphere discovered by Explorer I and Pioneer III. A satellite orbits the globe. Men watch as a rocket is erected and fired. A scientist at the National Bureau of Standards works on a formula. A man at the controls of a scatter radar fro space research. Animation: Ionized and neutral particles as well as free electrons that permit long distance communication. free electrons reflect radio energy. Radio waves penetrate the ionosphere. A scientist at the Ionosonde model C4 to measure electron density variations. Electron density model on the monitor. Two Oxygen atoms. An electron detaches and becomes a free electron. Radio waves pass by, the electron and waves oscillate and scatter energy. Animation: Need to excite electrons sufficiently so that their energy radiated can be detected from the ground. The process requires a powerful transmitter, large antenna, and a sensitive receiver.

Electromagnetic Hazards Group staff talk about ball lightning tests to determine structural integrity of composite materials.

Electromagnetic Hazards Group conducts ball lightning tests under Project Tesla, inside a hangar at Wendover Air Force Base in Utah. An interviewer gets information from the scientists. A team member talks about modern aircraft, new material and avionics system susceptible to lightning. He states that the composite materials used in new aircraft are stronger and don't conduct electricity like conventional metals. The team's research work involves protective measures and verification of the same. He discusses the effect of lightning on aircraft electronics, and the use of Wendover as the research facility due to its reproduction of long arcs. The aim is to study the effects of atmospheric electricity on new materials and electronics systems in modern aircraft. Robert Golka talks about a new company to study and create ball lightning, and apply it to nuclear fusion research.

Tesla Coils used to create artificial lightning in a hangar at Wendover AFB in Utah.

During the period from 1973 to 1982 the U.S. Air Force Electromagnetic Hazards Group, led by Robert K. Golka, conducted long arc simulated lightning attachment tests under Project Tesla. This film shows electrical "lightning" discharges being created with Tesla coils inside a hangar at Wendover Air Force Base in Utah. (Several discharges display what appear to be "ball lightning.")
