DOW-UAP-D017 - UAP Reported at Sandia Base, 1948-1950

209 sightings of 'green orbs,' 'discs,' and 'fireballs' were reported near Sandia Base from 1948-1950.

A Sandia-linked preliminary report found one Highway 84 air-particle collection with many copper-bearing particles, while an immediate follow-up collection showed practically none.

The July 24, 1949 Socorro fireball prompted an airborne-particle collection attempt beginning about 13.5 hours after the event.

A later Socorro sample contained many small particles and three apparently spherical particles that gave strong cobalt indications.

After no fragments were recovered from the January 30, 1949 green fireball, LaPaz and Crozier proposed rapid aircraft dust collection under future paths.

A May 1950 OSI summary says the frequency of unexplained aerial phenomena in New Mexico led to organized reporting beginning in December 1948.
