On 11 Jul 1970 a US Air Force Athena research rocket strayed far off course and crashed into the Bolsón de Mapimí in Mexico carrying two cobalt-57 radioactive capsules. A secretive joint US-Mexican recovery operation lasting about three weeks searched for the radioactive material. The unusual, hush-hush recovery is widely credited with seeding the 'Zone of Silence' alien-vortex folklore.
