An account in Nord, France

A witness sitting on a café terrace observes the slow and silent passage of a craft of a particular spherical shape with fins. It moves from East to West and rises vertically into the sky. The witness will not be able to continue following the object, which ends up directly in the sun. No other testimony will be collected. The object described by the witness does indeed resemble, as the witness puts it, an inflatable advertising module. The witness indicates a West wind felt on the ground, which contradicts this hypothesis, but the weather readings from Lille, very close by, indicate an East wind, which would then be compatible with the object's movement. It can be accepted that the wind felt in the square is very different from the wind at 100 meters of altitude. The rotation and disorderly movements of the object are not surprising for an object of this shape flying at the mercy of the wind. This case is classified "B": probable observation of a balloon inflated with helium, probably escaped from its owner.
