THE CASH-LANDRUM INCIDENT

THE CLAIM

That three civilians were injured by a military or government aircraft or device on a Texas road in 1980, and that the United States denied the existence of the aircraft they described in order to avoid liability.

THE THEORY, AS ITS PROPONENTS TELL IT

The distinguishing feature of this file is that the harm is documented in hospital records, which is rare in this section of the cabinet.

Betty Cash, Vickie Landrum and seven-year-old Colby Landrum reported encountering a large diamond-shaped object emitting flame and intense heat on a road near Dayton, Texas, and then seeing it accompanied by a substantial number of helicopters, which they described as tandem rotor CH-47 Chinooks.

All three became ill. Symptoms included nausea, vomiting, diarrhoea, skin burns, blistering, hair loss and eye problems. Betty Cash was hospitalised. Physicians who examined them noted presentations consistent with exposure to ionising radiation, and her later health declined considerably.

The helicopters are the crux of the proponents' case. A formation of that size over a populated area implies a military operation, and other witnesses in the area also reported helicopters that night. The government stated it had no aircraft in the area and no operation. The plaintiffs sued for $20 million, and the case was dismissed in 1986 on the basis that no government aircraft had been involved, which is the answer the plaintiffs were disputing.

WHAT IS KNOWN

The medical records are real and the injuries were treated. The pattern is consistent with a combination of thermal injury and possible radiation exposure, though no dosimetry was ever performed and the radiation attribution rests on clinical presentation rather than measurement.

The lawsuit was dismissed. The court accepted the government's position that no United States aircraft was involved.

Investigators including Bergstrom Air Force Base personnel interviewed the witnesses at the time, and a report was filed, which is itself notable given official policy had been to avoid investigating such reports since Project Blue Book closed.

No candidate aircraft has ever been identified. Speculation has ranged from a nuclear-powered propulsion test to a burning aircraft under escort, and none has documentary support.

EVIDENCE FOR

• Documented medical injuries in three people, treated in hospital, with a consistent onset.
• Multiple witnesses to a large helicopter formation in the area that night.
• An official interview and report at a time when policy was to avoid such investigations.
• A government denial that no aircraft were involved, which if untrue would explain the whole file and which the plaintiffs had no means to test.

EVIDENCE AGAINST

• No radiation measurement was ever taken from the witnesses, the vehicle or the site, so the radiation attribution is clinical inference.
• Betty Cash had significant pre-existing health problems, which complicates attributing her later decline to a single event.
• The described object has no candidate. Nothing in any released programme matches a large diamond-shaped, flame-emitting craft requiring a Chinook escort.
• The court found no government aircraft involved, and no document has since surfaced contradicting that.

ASSESSMENT

Open, and the strongest injury case in the cabinet, which is a narrow distinction carefully meant. Three people were hurt, the records exist, and their account of a large helicopter formation was partly corroborated by others. What has never been produced, in forty-five years, is any aircraft, any operation, or any measurement. The file therefore sits where OSA-098 sits: the event is not seriously in question, the explanation is entirely absent, and the only body that could resolve it is the one that says it was not there.

WHAT WOULD CHANGE THE GRADE

• The injuries are documented and were treated in hospital, which is rare in this section of the cabinet. What was never done is any measurement: no dosimetry on the witnesses, the vehicle or the site, so the radiation attribution is clinical inference.
• To CONFIRMED: identification of the aircraft. The witnesses described a large formation of tandem-rotor helicopters, other people in the area reported helicopters, and the government stated it had nothing there.
• The lawsuit was dismissed in 1986 on the basis that no US aircraft was involved, which is the exact proposition the plaintiffs were disputing and had no means to test.
