Descrição oficial
Este AIIR registra um incidente ocorrido em 17 de dezembro de 1953 perto de Hässleholm, na Suécia, traduzido de uma reportagem da imprensa local. Às 14h37, o piloto-chefe da Transair, comandante Ulf Christiernsson, e o chefe de tripulação Olle Johansson relataram ter observado um objeto que se aproximava de seu DC-3 em sentido contrário, cerca de 600 metros (1.969 pés) abaixo da aeronave, que voava a cerca de 2.150 metros (7.054 pés). A tripulação descreveu um “objeto metálico brilhante, esférico e elíptico” e estimou sua velocidade em aproximadamente a do som. Christiernsson descreveu o objeto como fortemente metálico, quase redondo e ligeiramente elíptico. Relatou que ele permaneceu visível por seis a sete segundos, não produziu exaustão nem rastro de condensação visíveis e, de início, lhe pareceu um avião a jato ou possivelmente um “robô” não tripulado. Segundo o relatório, o Estado-Maior de Defesa sueco não identificou nenhuma aeronave sueca na área naquele momento e afirmou que examinaria possíveis observações de radar. O relatório também inclui um breve perfil de Christiernsson baseado no relato de um contato pessoal, que o descreveu como “extremamente pouco confiável”, e observa que as autoridades suecas haviam iniciado uma investigação sobre o incidente. Toda a linguagem descritiva e estimativa contida neste relatório reflete a interpretação subjetiva de quem relatou o evento no momento em que ele ocorreu. Essas caracterizações não devem ser interpretadas como uma indicação conclusiva da presença ou ausência de quaisquer características intrínsecas do objeto ou de suas características de desempenho.
Sobre este tipo de documento
Este documento é um Relatório de Informações de Inteligência Aérea (AIIR), um formulário padronizado da Força Aérea dos EUA usado para registrar informações brutas de potencial valor de inteligência para análise posterior. O formulário foi um dos principais instrumentos de coleta de inteligência de campo da Força Aérea dos EUA no início da Guerra Fria, até que padrões de relato para toda a área de defesa fossem estabelecidos no início da década de 1960.

Trata-se de um Air Intelligence Information Report da Força Aérea dos EUA datado de 13 de janeiro de 1954, do escritório do adido aeronáutico em Estocolmo, intitulado "'Flying Saucer' Sighted by Swedish Pilot". Encaminha a tradução de uma notícia de jornal sueca sobre um objeto "desconhecido" visto em 17 de dezembro de 1953 às 14h37 sobre Hässleholm (Suécia) pelo capitão Ulf Christiernsson, piloto-chefe da companhia aérea Transair, e seu chefe de mecânicos Olle Johansson, enquanto voavam num DC-3 de Bulltofta para Bromma a cerca de 2.150 metros. O piloto descreveu um objeto metálico brilhante, quase redondo e levemente elíptico, que viajava em sentido contrário uns 600 metros abaixo deles, logo acima das nuvens, no que ele estimou ser a velocidade do som, visível por seis a sete segundos; disse que não podia ter sido um meteoro e que lhe pareceu "uma espécie de robô". O Estado-Maior da Defesa sueco declarou que não sabia de aviões suecos na área e que estava investigando, e o chefe da Força Aérea disse que se estava verificando o que as estações de radar poderiam ter detectado. O relatório acrescenta um perfil do piloto feito por uma fonte da Real Junta Aérea da Suécia que pessoalmente duvidava de seu relato, e diz que o escritório do adido tentava obter mais informações.

Sweden IR-J2 PAGE 2 OF 3 PAI.ES 1. On Thursday, 17 December 1953., while flying near HHssleholm, SWeden, Captain Ulf Christiernsson sighted an 11 unknown" object. The follorring is the translation of a newspaper account of the incident: "The chief pilot of Transair, Capt. Ulf Christiernsson, and his crew chief, Olle Johansson, had a strange meeting over HHssleholm at 1437 hours Thursday. A shining metal spherical elliptical object came toward them traveling in the opposite direction from their machine at an estimated speed of sound and approximately 600 meters below their DC-3, which was on its way from Bulltofta to Bromma. It was visible six to seven seconds; Capt. Chris tiernsson, who had good silhouette recognition, stated that what he saw was something absolutely new, possibly an unmanned robot. 11The Transair plane was automatic controls when the meeting occurred. Capt. Christiernsson did not have time for any measures other than to report to Bulltofta and the Defense Staff, which later sent out the following com munique: " •'rhe air crew of a civil aircraft observed on Thursday at 1437 hours over the area of HRssleholm an unknown object moving in the opposite direction from the airplane. The object was observed for six to seven seconds. At that time and altitude the weather was clear. Because of the low lying cloud for mations the object is not thought to have been seen from the ground. The De fense Staff does not know o.f any Swedish plane that was in that area at the time in question. An investigation is being conducted.• "Previously I have been extremely skeptical about all the stories of mysterious objects -- called flying saucers -- that have been seen at diverse points, said the Captain. Now I don't know exactly what to think; but it did seem to me that we had seen a robot of some kind. When I first caught sight of the object, which like us was in the civil air corridor, I thought it was a jet. We had, however, received no word that any such thing was on the way. "The object came toward us at what I would say was the speed of sound; we were flying at an altitude of approximately 2,150 meters and the object was around 600 meters below us. It was going in a southwesterly direction and disappeared after six or seven seconds. •tThe object had a strong metal shine; the crew chief, Johansson, who coulc see it longer than I, thought it was almost phosphorescent. The flying weathel was excellent above the clouds, which were at an altitude of about 1500 meters, and the sun was shining brightly. The object was proceeding just above the clouds. "The first silhouette I got diagonally from the right was narrow. When it was nearly directly under us, however, I saw that it was nearly round, just slightly elliptical. "The object, which could definitely not have been a meteor, gave off no waste gases or condensation traces. 11Was I afraid? No, but curious, very curious, concluded Captain Chris tiernsson. ItChristiernsson has seen just about everything in aviation and has very good silhouette recognition.

He finished as a captain in the British Air Force, after making some thirty raids in a Mosquito against enemy territory, in both North Africa and Italy. "Air Force Chief, General Nordenskiild, announced that it had been ascer tained that the object could not have been any Swedish aircraft. •• 'We are now investigating/' he continued, 'what our radar stations might have spotted.•" 2. Captain Christiernsson is 41 years of age and was born in sl<Rne in the souther part of Sweden. An extremely reliable source in the Royal Swedish Air Board, who was born in the same town and who is a life-long acquaintance of Capt. Christiernsson's, has stated that Christiernsson is charming and well-liked, but that he is also most wi trustworthy and was dismissed from a former position for "financial difficulty''• Dur ing the last war, Christiernsson tried to take a Swedi.sh Air Force B-18 and fly to Eng land, but was intercepted at Gothenburg and was put in jail. Although it is generally agreed in the Swedish Air Force that Captain Christiernsson is one of the best (and most discussed) pilots in Sweden today, he has never served with the RSAF except as a reserve captain. ;. Although the source above personally doubts Christiernsson•s story, the news papers report that the Defense Staff is continuing its investigation of the incident. This office is attempting to obtain further information on the occurrence. ~ Major, USAF Assistant Air Attacbe NOTE: THIS DOCUMENT CONTAINS INFORMATION AFFECTING THE NATIONAL DEFENSE OF THE UNITED STATES WITHIN THE MEANING OF THE ESPIONAGE ACT.
