Description officielle

Les sections 1 et 2 de ce mémorandum documentent une analyse de 1955 portant sur des signalements de « soucoupes volantes » ou d'« aéronefs non conventionnels », faisant référence à l'incident décrit dans les débriefings des observateurs contenus dans CIA-UAP-D020. Le mémorandum résume l'incident comme consistant en deux lumières s'élevant verticalement, puis passant au-dessus des observateurs. Le mémorandum contient un langage de réserve qui suggère que l'auteur a conclu que les signalements, tels que décrits, n'indiquaient pas la présence d'un « aéronef non conventionnel ». La section 3 cite une conclusion antérieure du Dr [Howard] Robertson (du Robertson Panel de 1953) selon laquelle « presque toutes les observations […] ne représentaient aucune menace pour les États-Unis ». La section 4 traite de l'état des recherches alors en cours sur des « aéronefs en forme de soucoupe » dans le cadre du Project « Y », un programme conjoint américano-canadien de développement aérospatial de l'époque.

Résumé IA

Ce document de la CIA de 4 pages, top secret, daté de fin octobre/novembre 1955 et signé par H.P. Scoville, Jr. (conseiller scientifique, Office of Scientific Intelligence), analyse une dépêche d'une station de la CIA à Manille (datée du 13 octobre 1955) rapportant des observations d'aéronefs non conventionnels. Deux officiers ont observé deux lumières qui semblaient d'abord traverser une traînée puis survoler leur position à haute altitude (environ 9 000 pieds) ; un témoin n'a pas pu déterminer si l'objet était réel, une illusion ou un reflet. Un groupe d'enquête de suivi a examiné les observations et conclu que le phénomène ne représentait aucune menace pour la sécurité des États-Unis. Le mémo traite également des recherches en cours sur des aéronefs non conventionnels, en forme de soucoupe, menées par Avro Aircraft Ltd. du Canada, notant que le programme en était encore aux premiers stades de développement, avec des performances proposées incluant un fonctionnement à très haute altitude, des vitesses d'environ 1 500-1 800 mph, et une autonomie d'environ 700 miles. Il fait référence à un général (nom partiellement illisible, peut-être Samford) rendant compte du projet connexe de l'armée de l'air lors d'une réunion du TAC, reflétant l'intérêt de la CIA et de l'armée de l'air tant pour les rapports d'OVNI que pour des programmes aérospatiaux classifiés parallèles durant l'année 1955.

A dispatch from Manila, [station designator illegible], dated 13 October 1955, described the sighting of unconventional aircraft. A check with the sources, one of the informants, was made and it was possible to confirm in several respects the information received in the dispatch. 2. Two observers were flying [or on watch] when they sighted two lights which initially seemed to cross the trail and flew overhead at a high altitude. He failed to observe the body of the object and had no feeling as to whether it was real, an illusion, or something else. His only impression was that it rose vertically and then leveled off in a manner unlike any known aircraft. However, in view of the fact that the aircraft appeared to be quite high (9,000 feet) [reading uncertain], his observations were undoubtedly consistent with [name, illegible]'s remarks that he was too excited to give a detailed account. The fact that no other observer had corroborated his account was also noted, in his opinion, as to the unconventional character of the object. This also tended to confirm the excitement of the local officials following the incident. It is my belief that eyewitness testimony alone could not confirm the existence of any unconventional aircraft. However, he was not in a position to know just what the other members of the party had seen. A more careful evaluation of the other accounts is in order. 3. Two other officers, [name illegible] and [name illegible], are in a group which investigated a sighting at [location illegible]. The group was able to explain almost all of the sightings and reached the conclusion that the phenomena represented no threat to the security of the U.S. Even if the present sightings... [PAGE 4] ...continued [reasoning] were not, it did not seem probable that unconventional aircraft had actually been operating sound in [near] the U.S. The source of this [speculation] is [name illegible], who reports on a program at Avro Aircraft Ltd. of Canada for the development of unconventional, saucer-like aircraft. However, the program is still in the very early [experimental] stages, with work only [months or years] before completion, in the opinion of [name illegible]. He indicated that proposed performance characteristics are, at present, only a very high ceiling (estimated 80,000 [figure uncertain] feet), speeds of 1,500 to 1,800 miles per hour, a range of about 700 miles, and a diameter of [figure illegible] feet with a radius of action of [figure illegible]. A technical [evaluation] of the theoretical claims made would be needed. [Name illegible] is being directed by [organization illegible]. Mr. [illegible] is arranging to obtain the original data for the flying [wing/saucer] program from the group at O[ttawa]/[Malton], World[wide]. [It is understood that General [Samford?] is to report on the status of the Air Force project at the TAC meeting.] H.P. SCOVILLE, JR.
