Voilà ce que j'ai trouvé pour les années 50 sur cette base de données :
October 6th, 1953: Norwich, England; 7.15pm - Mr.F.W.Potter, a member of the Norwich Astronomical Society, was observing the night sky of Norwich with a 3.5-inch refractor telescope, when he saw a very bright object coming from the south-west: "I focused on it and found the light given from the object was not reflected sunlight, as I first believed, but an internal light being sent out from a fixed apparatus situated around the dome. The rays or beams of light could be seen distinctly from the dome and attached directly beneath it was a much larger and flattened dome with a protruding band running in a circumference around its edge. This was clearly seen in the telescope by the rays of light thrown out from the apertures in the top dome. The underneath of the large flattened bottom dome was hollow and appeared to be glowing red, but there were no vapour trails or gases to be seen. / It did not rotate but kept the same portion of the dome towards the telescope until it changed its angular course. Then it gave me a chance to visualise another of the apertures that previously had been hidden from view. It was then travelling to the north-east and disappearing from view." (ACA)
Berlin, Germany; (Date exacte inconnue, années 50) about 10.15 pm - three round luminous bodies that flew at great height, on a zig-zag course, were observed by two amateur astronomers. The men, Wolfgang Kobski and Rudi Fibich said that what they had seen could not have been meteors, stars or an hallucination. (FSNews6)
January 8th, 1958: 'An amateur astronomer and four witnesses sighted a luminous yellow-reddish object in the sky at about 8:50 pm. It was travelling in a northerly direction, then swung almost at right angles in a curve to the east. / Mr.B.Welstead, of Punchbowl, a suburb of Sydney, was looking for star clusters, and on observing the object with the naked eye, he called the attention of a colleague who possessed a telescope. It was then they called three other people in the house to observe the phenomena. / The observation lasted at least 30 seconds. the Australian Air Force later stated that there were no jets in the air on that night.' (MHervey)
October 6th, 1959: Lincoln, Nebraska, USA. 'A U.S.Army Colonel, his wife and their son saw an object making abrupt turns at high speed. The son had been studying astronomy and pointing out the stars.. His mother noted the object and pointed it out.. At first they thought it was a meteor. It was round and.. the colour between white and yellow. (It) was first seen 70 deg. above the horizon at 15 deg. azimuth (S-SE). It moved north-northwest (330 deg.) for about 12 miles and then made a quick turn (90 deg.). Shortly thereafter.. it made another abrupt turn south (180 deg.).. It dimmed out and returned to bright several times...' (UFOIRC/O.Binder)
Bien entendu, il ne s'agit là que de témoignages donc la plus grande prudence est nécessaire sachant aussi que pour certaines de ces observations, d'autres explications que des météores & bolides peuvent rendre compte des faits décrits par les astronomes.
Prochaine étape, les années 60...
