San Francisco Airport

Abandonment due to economic non-viability. The airport was a small, rudimentary airstrip in a very remote and sparsely populated region of the Chihuahuan Desert. Such airfields are typically built for specific, limited purposes (e.g., private ranching, mining exploration, or personal use) and are often abandoned once that purpose ceases or becomes uneconomical. There is no evidence to suggest it was closed due to a specific accident or for military conversion.

The site is an abandoned and derelict airstrip. Satellite imagery confirms the location contains a single, unpaved runway that is still visible but clearly unusable. The runway surface is eroded, overgrown with desert vegetation, and shows no signs of recent use or maintenance. There are no remaining buildings, hangars, or any other airport infrastructure at the site. It is effectively being reclaimed by the surrounding desert environment.

The airport, also known as 'Aeródromo de San Francisco', was a private-use general aviation airstrip. Its primary function would have been to provide air access for light aircraft to this isolated area, likely serving local ranches or potential mining interests. It was not a commercial airport and did not handle scheduled passenger or cargo flights. The airstrip has gained some notoriety in ufology circles due to its proximity to the alleged 'Coyame UFO Incident' of August 1974, where a UFO is said to have collided with a small civilian aircraft. Some speculative accounts suggest this airstrip, or one nearby, may have been involved in the subsequent alleged military recovery operations, though this is not supported by official documentation.

There are no known plans or prospects for reopening this airport. Given its remote location, the advanced state of decay, the lack of supporting infrastructure, and the limited economic activity in the immediate vicinity, there is no practical or financial incentive for its rehabilitation.
