The Cash-Landrum Incident (1980)
On December 29, 1980, near Houston, Texas, Betty Cash, Vicki Landrum and Landrum's grandson watched a diamond-shaped metallic craft blast jets of flame above their car, forcing them to flee the heat. Shortly after, a formation of 20 to 26 military helicopters, including several Chinooks, escorted the object as it fled. Within hours, all three witnesses developed severe symptoms — nausea, blistering, hair loss.

3 witnesses (2 women, 1 child)
Why it endures
Betty Cash's physician called her condition a "textbook case" of radiation poisoning, comparable to exposure a few miles from Hiroshima.
Official version (contested)
The US government denied any involvement; the victims' damages lawsuit was dismissed for lack of proof of a military craft.
