Cash-Landrum Incident — Radiation Injuries Texas 1980
The only known case in which US citizens suffered documented radiation-injury medical outcomes following a UAP encounter, and the only case in which those citizens sued the US government for damages. Betty Cash, Vickie Landrum, and young Colby Landrum encountered a diamond-shaped craft emitting heat and light on a Texas highway, escorted by 23 military Chinook helicopters. All three developed radiation-exposure symptoms. Cash died from her injuries. The US government denied involvement; the federal lawsuit was dismissed.
