Cylindrical UFO in motion in 1954

Summary

In 1954, two witnesses in France observed a dark cylindrical object with an oscillating movement in a field. The day was clear and fog-free, aiding visibility. The object silently rose at an angle and then vertically, emitting a greyish haze. The witnesses, frightened, went to the gendarmerie and insisted it was not a helicopter. The investigation found no physical traces at the site, but the witnesses' credibility was considered valid. The case was classified as an unidentified strange phenomenon.
