Description officielle
Cet AIIR consigne un incident survenu le 18 janvier 1957 au-dessus de l’Arabie saoudite, au cours duquel l’équipage d’un B-52 de l’U.S. Air Force a signalé avoir détecté un écho non identifié sur le radar de tir de l’appareil pendant environ cinq à sept minutes. Le rapport décrit cet écho non identifié comme plus petit que celui produit par un autre B-52 opérant dans la zone. L'ensemble du langage descriptif et estimatif contenu dans ce rapport reflète l'interprétation subjective de l'auteur au moment de l'événement. De telles caractérisations ne doivent pas être interprétées comme une indication concluante de la présence ou de l'absence de caractéristiques intrinsèques ou de performances de l'objet.
À propos de ce type de document
Ce document est un Air Intelligence Information Report (AIIR), un formulaire normalisé de l’U.S. Air Force servant à consigner des informations brutes présentant une valeur potentielle pour le renseignement en vue d’une analyse ultérieure. Ce formulaire a été l’un des principaux outils de collecte du renseignement de terrain de l’U.S. Air Force au début de la guerre froide, jusqu’à l’adoption de normes de signalement communes à l’ensemble de la défense au début des années 1960.

Il s'agit d'un Air Intelligence Information Report de l'US Air Force, classé secret à l'époque, daté du 19 janvier 1957, émanant de la 22e escadre de bombardement de la base aérienne de March (Californie) et intitulé "Report of Unidentified Aircraft Sighting", au-dessus de l'Arabie saoudite. Il indique que le 18 janvier 1957, lors d'une mission du Strategic Air Command, l'équipage du B-52 numéro 394, qui volait à 39 000 pieds et environ 642 nœuds près de 27°N 47°E juste avant un rendez-vous avec un avion ravitailleur, a détecté un aéronef non identifié sur le radar de tir A-3A. L'écho est resté sur le repère des 6 000 yards, au centre de l'écran, pendant cinq à sept minutes environ, puis a disparu vers la gauche lorsque le B-52 a viré à gauche ; le rapport note que cette disparition a pu être causée par le changement de direction du bombardier et que l'écho non identifié était plus petit que celui d'un autre B-52 de la formation. Des schémas de l'affichage du radar de tir sont joints. Certaines parties de la page de synthèse sont peu lisibles, et le rapport n'identifie pas le contact.

Give significance in final one-sentence paragraph. List inclosures at lower left. Begin text of report on AF Form 112—Part II.) B-52 aircraft number 394 from Castle AFB, California, Commanded by Lt/Col J.H. Morris, of the 328th Bombardment Squadron, 93d Bombardment Wing (H), made radar contact with an unidentified aircraft while participating in Strategic Air Command mission "Operation Powerflight". Coordinates at time of contact; 27 north - 47 east (approximately). Speed of aircraft (B-52) at contact; 642 knots per hour. Altitude; 39,000 feet. Visibility; night. Duration of contact; five (5) to seven (7) minutes. (approximately). Cell position of B-52 making contact; cell leader. Call sign of B-52; Runner 11. Gunner's name; M/Sgt C.H. Ballew. Just prior to making rendezvous with tanker aircraft B-52 aircraft number 394 picked up an unidentified aircraft on the A-3A gunnery scope. The return of the unidentified aircraft remained at the 6000 yard marker (center) of the scope for approximately five (5) to seven (7) minutes after which the B-52 made a bank to the left, and the unidentified aircraft return disappeared off the scope to the left. The disappearance may have been caused by the change in direction of the B-52; however the unidentified aircraft seemed to disappear in the direction of the Baghdad Flight Identification Region. The unidentified aircraft gave a smaller return on the scope than a simultaneously received return produced by a second B-52 aircraft riding at the 3000 yard marker of the scope. Significance: The unidentified aircraft appeared on the scope where no aircraft were expected.
