IncidentCash–Landrum Incident (29 December 1980)

aka Cash–Landrum Incident (29 December 1980)

Three civilians outside Huffman, Texas encountered a diamond-shaped object emitting flame and were escorted by 23 unmarked military helicopters; all three subsequently developed radiation-sickness symptoms.

under-corroborated Reclassified from phenomenologically-open to under-corroborated on a 2026 adversarial re-audit. The famous radiation-injury pillar fails even sympathetic scrutiny: rejected by skeptics' own medical experts (Niemtzow, Posner, Sparks), by independent radiological surveys finding no abnormal radiation, and by the witnesses' own records (alopecia areata; cardiac history), with a decisive dose-vs-survival contradiction (a dose matching the rapid onset would be lethal in days; all three lived years). The remaining narrative is a single related witness-group with a curated record and no medical baseline; the helicopters, if real, point to a mundane military operation, not an exotic craft. Real illness of contested/ordinary cause + uncorroborated craft story = under-corroborated. NOT documented-hoax (self-injury claims are unproven; distress is sincere).

At approximately 21:00 on 29 December 1980, Betty Cash, Vickie Landrum, and Vickie’s seven-year-old grandson Colby Landrum were driving on FM 1485 near Huffman, Texas when they encountered a large diamond-shaped object hovering over the road, emitting flame from its base. They reported seeing 23 helicopters — described by the witnesses themselves as tandem-rotor CH-47 Chinooks, a count partially corroborated by other area witnesses in the Schuessler casebook — escorting the object away. All three developed symptoms consistent with radiation exposure within hours: severe headache, vomiting, skin lesions, hair loss. Betty Cash was hospitalized for 15 days. They sued the U.S. government in 1981 for $20 million; the case was dismissed in 1986 on grounds that the government had no knowledge of and no involvement with the object.

Notable & intriguing

All three witnesses were treated for symptoms consistent with ionizing radiation exposure: Betty Cash, hospitalized for 15 days, developed corneal damage and skin lesions; Vickie Landrum lost her hair; Colby Landrum, age 7, developed permanent vision impairment.

Cash v. United States (Case No. H-81-2700, S.D. Tex.) was dismissed by Judge Ross Sterling in August 1986 on the grounds that no agency of the U.S. government acknowledged knowledge or operation of the object or the escorting helicopters. The plaintiffs had sued for $20 million.

Cash v. United States, U.S. District Court, Southern District of Texas, dismissed 21 August 1986
Lt. Col. John B. Alexander, on official assignment from Sen. Charles Bennett’s office to inquire about the case, formally requested helicopter activity logs from every U.S. military installation within 100 miles of Huffman, Texas on the night of 29 December 1980. Every installation returned a ‘no records’ response.
