Project Twinkle Final Report (scan)

NICAP · 29 pages · text by OCR

This declassified U.S. Air Force file contains the final report of Project Twinkle, dated 27 November 1951 and written by Louis Elterman of the Geophysics Research Division, together with related correspondence. The project was set up to investigate the green fireballs and other light phenomena around Holloman AFB and Vaughn, New Mexico, and it was run with Askania cameras. The report calls its findings essentially negative and recommends no further funding. In March 1952 the Directorate of Intelligence declined to declassify it.

## UNCLASSIFIED

(1) No further fiscal expenditure be made in pursuing the problem. This opinion is prompted partly by the fruitless expenditure during the past year, the uncertainty of existence of unexplainable aerial objects, and by the inactive position currently taken by Holloman AFB as indicated by the "stand-by status" of the project. The arrangements by HAFB for continued vigilance by Land-Air, the weather station as well as the briefing of pilots on the problem in part relieves the need for a systematic instrumentation program.

(2) Within the next few months, Dr. Whipple will have completed the installation of two 18-inch Schmidt cameras for meteor studies. The cameras will be stationed about 20 miles apart in the vicinity of Las Cruces, New Mexico. Since these studies will be sponsored by the GRD, arrangements can be made for examining the film for evidence of aerial object phenomena.
