Levelland UFO Case is located in Texas

The Levelland UFO Case occurred on November 2–3, 1957 in and around the small town of Levelland, Texas. Levelland, which in 1957 had a population of about 10,000, is located west of Lubbock on the flat prairie of the Texas panhandle. The case is considered by ufologists to be one of the most impressive in UFO history, mainly because of the large number of witnesses involved over a relatively short period of time.^[2] However, both the US Air Force and UFO skeptics have labeled the incident as being caused by either ball lightning or a severe electrical storm.^[3]
