Coyame de Sotol

Coyame and the Crash That May Not Have Happened

On 25 August 1974 US radar over the Chihuahua desert picked up an unidentified return heading north and, almost at the same time, a light aircraft. The returns merged and vanished. In the version set out in a document that reached an American researcher in 1978, a Mexican military party found the wreckage of a disc in the desert, and then contact with the party was lost. The document is a typed report with no signature and no classification, of unknown provenance. No agency in either country has ever confirmed it. The case survives in the literature as an example of a story grown entirely out of one piece of paper, and is useful for exactly that: there is nothing in it to check.
