Ent AFB, Colorado: ATIC memo urges 4602nd AISS to cut unknowns, categories broadened
On 15 February 1955, ATIC sent a memo to Maj. Joseph A. Cybulski, commander of the 4602nd AISS at Ent Air Force Base in Colorado Springs, complaining about the high number of unknowns; the Air Force then broadened its "identified" category to include probable and possible solutions.
Background
ATIC sent a memo to Maj. Joseph A. Cybulski, commander of the 4602nd Air Intelligence Service Squadron at Ent Air Force Base in Colorado Springs, Colorado, complaining about the high number of unknowns. It suggested that the AISS and ATIC "strive to reach as many case solutions as possible, thereby reducing the percentage of the unknowns to a bare minimum," since with sufficient information most cases "will fit to some extent one of the hypotheses." The Air Force changed its earlier classification (identified, insufficient data, unreliable, unknown) by broadening the identified category to include probable and possible. In its final statistics Blue Book lists these sightings simply as identified. The cited memo, "Evaluation of Unidentified Flying Objects," is signed by Maj. T. G. Connair Jr. The account follows the entry in George M. Eberhart's chronology UFOs and Intelligence (CUFOS) and the sources cited there; it is not an independent determination by From Beyond Space.
