The term green fireball is often associated with meteorites of sufficient velocity and mass that can produce bright green fireballs sufficient to create a shockwave. Green fireballs are a kind of unknown flying object that was visible in the sky in the early 1950s. Early observations occurred primarily in the southwestern United States, particularly New Mexico. The green color is thought to be due to ionized oxygen, and it is thought to be similar to the color of the green aurora due to the 557.7 nm emission of Hall from detestable neutral oxygen (Holiday 1960). They were once a significant concern to the U.S. government because they were often clusters of sensitive research and military installations, such as the Los Alamos and Sandia National Laboratories, then Sandia bases.
Military expert Dr. Lincoln LaPaz has led much of the military’s investigation into the shelling. Frustrated Yamaoka, head of public relations at the National Astronomical Observations of Japan in Tokyo, Hitoshi Yamaoka told the Japan Times that the Halloween mystery was probably blood or an extremely bright meteorite that exploded in the atmosphere, a phenomenon that is not uncommon. After interviewing more than a hundred witnesses, Dr. LaPaz advised the military and the Atomic Energy Commission to give their opinion that the fireballs were probably the top-secret “obsolete defensive device” tested by the United States or Soviet intelligence devices. At the Los Alamos Conference in February 1949, the aforementioned cipher, project sign, world-renowned high atmospheric physicist Dr. Joseph Kapalan, H-bomb scientist Dr. Edward Taylor, other scientists, and the military brass came to an end, although unanimously, green fireballs were a natural phenomenon. To the conference participants, although the source of the green fireball was unknown, their existence was beyond doubt. No initial reports of any impact were found, and no such debris was found to the public. At the very least, if the object hits the earth, it doesn’t seem to be able to do any damage, but it never makes it to the surface.
In December 1949 Project Twinkle, a network of green fireball observation and photographic units was established but never fully implemented. It was closed two years later with the official conclusion that the incident was probably natural. Yet, at this stage, it is hard to shake the feeling that the balls of green fire are equivalent to interpreting a mystery with another mystery equated with lightning. Green fireballs have been given natural, man-made, and extroverted sources and they have been associated with both the Cold War and urology. Because of the official paper trail about the phenomenon, many urologists consider the green fireball to be the best-documented example of an unknown flying object (UFO).
