The article focuses on the 1980 Cash/Landrum case.

Betty Cash, Vickie Landrum and Colby Landrum, Vickie’s seven-year-old grandson, sighted a UFO over the Piney Woods, near the town of Huffman, Texas, on 29 December 1980, at around 9:00 p.m.

Twenty-three U.S. military helicopters were trying to encircle the UFO, according to the witnesses. They sighted two types of helicopters, double rotor CH-47 Chinooks and Bell-Hueys.

All three UFO witnesses suffered severe physical injury as a result of the encounter with the UFO.
