ALSACAT-1990-00-00-DIEFFENBACH-1
Someone had reported to the UFO web forum "R.I.O." an observation in the evening between 11:00 p.m. and 01:00 a.m., around 1990 or 1993, near Dieffenbach-au-Val in the Bas-Rhin.
Returning from an evening party with a friend, they had chatted outside the latter's home, and then both watched in silence the mountain in front of them, the rock of the Cuckoo in Dieffenbach.
In a logging hole, the witness saw a white object go down, identifying it as a motorcycle headlight, and he thought there was "a crackpot who makes a motorcycle night descent."
But this "motorcycle" traveled about 500 meters from the top of the mountain to roughly its 2/3 in about 4 or 5 seconds and then left in the sky at right angle relative to its initial descent trajectory of 45°, with lightning-speed acceleration, disappearing into the night after a half second.
Flabbergasted, the witness asked his friend what he had seen it and the latter described the same thing, though they had not spoken during the observation. This strengthened the witness to the fact that what they saw was not a hallucination.

It was about a dozen years ago, one evening with a friend, we saw something really surprising:
It was late at night, between 11pm and 1am, on the way home from a party, we discussed outside his home, and suddenly we both watch in silence the mountain in front of us (the rock of the Cuckoo Dieffenbach (67) and in a logging hole, I see a white object that I identify as a motorcycle headlight go down, and I think there's a crackpot who makes a night descent by motorcycle. The problem is that this "motorcycle" makes + - 500 m (from the top of the mountain to its 2/3 + -) in about 4 or 5 seconds and then goes up in the air at right angle from its original path (a descent at 45 °) with lightning-speed acceleration and disappears after 1/2 second in the night. Flabbergasted, I ask my friend what he saw and he describes the same thing to me as what I have described, but without telling him. What comforts me to the fact that what we saw was not a hallucination.

The "rocher du Coucou" ("rock of the Cuckoo") in the Altenberg, in the "Val-de-Villé" is 856 meters above sea level on the territory of the municipality of Neubois, at 173° and 2.7 kilometers in a straight line from the center of Dieffenbach-au-val. Its summit is visible from far away. There is a television transmitting antenna on the top, paths and sources on its slopes but no paved road.

It is however in no way certain that the witnesses were in Dieffenbach, since it is the rock and not themselves that they locate there.

There is indeed a logging gap on its slope, on the valley of Val-de-Villé side.
A path from the top to 2/3 of its slope is actually equivalent to about 500 meters. Traveled in 4-5 seconds, it gives a speed of 100 to 125 m/s or 360-450 km/h assuming of course that the thing was on the ground on the slope.
Apart from a possible alien craft, the only scenario I see is that of a helicopter that would have flown from the top, down the slope, then veering off to the sky thus hiding its headlight(s). The viewing distance of a few kilometers at least could have masked its engine noise.
Possible helicopter.
