The Dome of Light is an unsolved Cold War mystery that may be a Soviet-influenced weapon under development. The phenomenon has been known to the US government since at least 1986, according to disparaging reports. In November 1988, the US Air Force RC-135S Cobra Ball flew off the coast of the Kamchatka Peninsula, watching the planned launch of a Soviet SS-20 ballistic missile (RSD-10 Pioneer) from the Kura test site. Pilot Robert Hopkins III witnessed an almost incomprehensible event. He looked west and saw "a milky-white wall moving to the left, over the Soviet Union, to the right, towards the North Pacific". The wall stretched from ground level to the height where they could see and pass at a speed that he later estimated at 10,000 km per hour. A wall of light passed over his plane and disappeared, leaving the air force analysts and the pilot behind. Additional light dome events have been recorded, sometimes coinciding with the launch of Soviet RSD-10 missiles. A 1986 report stated that the dooms could reach an unbelievable 1,900 km in diameter and 1,000 km in height, penetrating far into the threshold of the Earth's prophecies. One of the more probable theories is that the pods were a countermeasure designed to blind American satellites in the critical first moments of a devastating shock nuclear attack by the Soviet Union. It can also be the result of creating ethylenelenecin clouds to study the atmosphere. There were even suggestions that the Soviets developed a device based on Nikola Tesla's theory of energy, which he described as one of the fundamental sources of energy in the universe along with electromagnetic energy. Whatever the origin of the dome of light, it is now clear that the intelligence community in the 1980s took it very seriously.
