7. The Soviet Airbase Phenomenon (1955)
One of the most fascinating and thoroughly recorded ball lightning incidents in military history happened in August 1955 at a Soviet military airbase close to Moscow. Many staff members, including radar operators and experienced pilots, saw an amazing ball lightning display lasting almost an hour during a regular thunderstorm. The phenomena started when multiple glowing spheres—from the size of a golf ball to that of a basketball—were seen rising from the sky and headed toward the airfield. The way the ball lightning interacted with the advanced military machinery on the facility made this event very unforgettable. Radar operators noted unusual readings matching the optical reports, implying that the events had clear electromagnetic characteristics. Certain of the spheres were observed hovering close to airplanes on the tarmac, momentarily malfunctioning electronic systems. From their cockpits, pilots who were airborne at the time claimed to have seen balls of light that were quite agile and able of quick acceleration. The most remarkable feature of this occurrence was the claimed behavior of the ball lightning when confronted by ground crew: the spheres seemed to react to human presence, moving away or disintegrating when people got too close. Classified Soviet military reports, later deleted and distributed to the scientific community, painstakingly recorded this event. Combining the thorough observations made by experienced military people with the supporting radar data, the Soviet Airbase Phenomenon has become pillar in ball lightning study. It has given important new perspectives on the possible electromagnetic character of ball lightning and its consequences for electronic devices. Moreover, this event attracted more attention in ball lightning in military and scientific spheres, which resulted in more methodical research of the phenomena in connection with aviation safety and possible creation of new technologies motivated by its features.
8. The Headmaster’s Office Incident (1967)
One of the most well-documented occurrences of indoor ball lightning, a stunning event happened at a Lisbon, Portugal school on September 15, 1967. The headmaster and a few other instructors were in the administrative office during a strong thunderstorm when they saw a brilliant sphere of 15 centimeters in diameter come through an open window. Described as bluish-white, the light ball drifted across the room at roughly head height, traveling in an apparently intentional path. Witnesses said the ball seemed to be slowly rotating and had a faint hissing sound. It went across the office and passed a wooden bookcase without damaging anything or starting the books to catch fire. The most remarkable feature of this event was its length and the ball’s interaction with the surroundings. The sphere moved among objects in the room for about two minutes, at one point exactly between two astonished teachers. The incident started when the ball suddenly vanished with a loud crack as it neared an electrical socket, leaving behind a strong ozone smell and momentarily darkening the building. The great degree of education of the witnesses and the thorough, consistent narratives they offered make this case especially relevant to researchers. Having a background in physics, the headmaster made detailed notes and observations even trying to graph the ball’s route across the office. Because it offers unusual understanding of the behavior of ball lightning in an indoor environment, atmospheric scientists and physicists have researched this incident carefully. The discovery of the ball passing through solid objects without burning has disproved current ideas regarding the nature of ball lightning and generated fresh hypotheses concerning its composition and energy state. Moreover, the Headmaster’s Office Incident has become a major source of reference in debates on the possible link between ball lightning and conventional electrical systems, therefore motivating study on the interaction of the phenomenon with man-made electromagnetic fields.
