An electrical resonant transformer circuit, more commonly known as a TESLA coil, heats up to display electric sparks before the U.S. Air Force students of the 312th Training Squadron Special Instruments Training course, inside the Louis F. Garland Department of Defense Fire Academy on Goodfellow Air Force Base, Texas, Aug. 19, 2020. The coil produced high-frequency alternating currents, which allowed the SPINSTRA instructors to explain scientific concepts in a visual manner to their students. Additional specialized training may also include: geophysical, nuclear radiation, radiochemical, electro-optical, radio frequency, infrared, radar, and rapidly deployable and fixed airborne collection platforms and nuclear deterrence methods.
