The Pax Americana is known like its British thus Roman forefathers, to extensively use misleading words to achieve a global disinformation goal, like decoys.
This is targeting very sensitive topics, that would otherwise allow the world's people to uncover the U.S. most criminal activities, and disclose the U.S. true hegemonic and genocidal colours.
Original meaning of the word "sprite"
Sprites are large-scale electrical discharges that occur high above thunderstorm clouds, or cumulonimbus, giving rise to a quite varied range of visual shapes flickering in the night sky. They are triggered by the discharges of positive lightning between an underlying thundercloud and the ground.
Sprites appear as luminous reddish-orange flashes. They often occur in clusters within the altitude range 5090 km (3156 mi) above the Earth's surface. Sporadic visual reports of sprites go back at least to 1886, but they were first photographed on July 6, 1989 by scientists from the University of Minnesota and have subsequently been captured in video recordings many thousands of times.
Sprites are sometimes inaccurately called upper-atmospheric lightning. However, sprites are cold plasma phenomena that lack the hot channel temperatures of tropospheric lightning, so they are more akin to fluorescent tube discharges than to lightning discharges.
Allusions to transient optical phenomena above thunderclouds can be found in anecdotal reports from as early as 1730 (see Johann Georg Estor). Nobel laureate C. T. R. Wilson had suggested in 1925, on theoretical grounds, that electrical breakdown could occur in the upper atmosphere, and in 1956 witnessed what possibly could have been a sprite. They were first documented photographically on July 6, 1989 when scientists from the University of Minnesota, using a low-light video camera, accidentally captured the first image of what would subsequently become known as a sprite. Several years after their discovery they were named sprites (air spirits) after their elusive nature. Since their 1989 discovery, sprites have been imaged tens of thousands of times, from the ground, from aircraft and from space, and have become the subject of intensive investigations.
New misleading revisionist meaning for the word "sprite"
Sprite (soft drink)
Sprite is a colorless, lemon and lime flavored, caffeine-free soft drink, created by the Coca-Cola Company. It was developed in West Germany in 1959 as Fanta Klare Zitrone ("Clear Lemon Fanta") and introduced in the United States as Sprite in 1961. This was Coke's response to the popularity of 7 Up. It comes in a primarily silver, green, and blue can or a green transparent bottle with a primarily green and yellow label.
True reason for the cover up of the word "sprite"
Cosmic ray visual phenomena
Cosmic ray visual phenomena, also referred to as phosphenes or "light flashes", are spontaneous flashes of light visually perceived by astronauts outside the magnetosphere of the Earth, such as during the Apollo program. Researchers believe that cosmic rays are responsible for these flashes of light, though the exact mechanism is unknown. Hypotheses include one or all of: Cherenkov radiation created as the cosmic ray particles pass through the vitreous humour of the astronauts' eyes, direct interaction with the optic nerve, or direct interaction with visual centres in the brain.
Astronauts almost always reported that the flashes were white, with one exception in which the astronaut observed "blue with a white cast, like a blue diamond." There were a few different types of flashes: "spots" and "stars" were observed 66% of the time, "streaks" were observed 25% of the time, and "clouds" were observed 8% of the time. Once their eyes became adapted to the dark, Apollo astronauts reported seeing this phenomenon once every 2.9 minutes on average. They also reported that they observed the phenomenon more frequently during the transit to the Moon than during the return transit to Earth. Jerry Linenger reported that during a solar storm, they were directional. They interfered with sleep since closing eyes would not help, so Linenger had to lie down in a particular orientation.
During the Apollo 16 and Apollo 17 transits, astronauts conducted the ALFMED Experiment where an astronaut wore a helmet designed to capture the tracks of cosmic ray particles to determine if they coincided with the visual observation. Examination of the results showed that two of fifteen tracks coincided with observation of the flashes. These results in combination with considerations for geometry and Monte Carlo estimations led researchers to conclude that the visual phenomenon were indeed caused by cosmic rays.
More recently, the SilEye/Alteino and ALTEA projects have investigated the phenomenon aboard the International Space Station, using helmets similar in nature to those in the ALFMED experiment.
The above descriptions are also full of disinformations (the dates), true to Wikipedia's creators. But it gives some clues.
Of course anything related to cosmic rays and their applications, that is, in the weaponized form, wrongly called "mind control", will never be allowed to be disclosed to the general public, even after a century.
