This Black Vault copy of Air Force records centers on the Project Twinkle Final Report, which Louis Elterman of the Geophysics Research Division wrote on 27 November 1951. Project Twinkle investigated green fireballs and other light phenomena in New Mexico using Askania cameras run by Land-Air at Vaughn and Holloman AFB. Elterman found the results essentially negative, with most sightings put down to aircraft, balloons, birds, clouds and meteors. He recommended no further spending. The file also includes the 1949 and 1950 correspondence that set up the project and 1952 memos about declassifying it.
