Date:
October 30, 1994
Location: Selestat, France
The
car leaves the city quickly but a little further finds
the phenomenon in front of the vehicle: a triangle with
the same type of light on the circumference came to be
added to the circle. The triangle is equilateral 10 side
meters approximately and altitude from 10 to 15 meters.
The phenomenon accompanied the vehicle which ran to approximately
80 km/h while adapting at the speed and that on several
km. During a change of direction the object accelerated
and moved away.

The
following is a brief summary of the case. The case is
from the files of the official French government UFO research
program GEIPAN (Group for the Study and Information of
Unidentified Aerospace Phenomenon), which is a part of
CNES, the French government space agency. The full report
and file on this case is on the GEIPAN website at http://www.cnes-geipan.fr/geipan.
The case has been classified as a 'Class D' case, which
are the unexplained cases in the GEIPAN files.
The
summary has been translated using automatic computer translation,
so it is not a perfect translation.
On
October 30, 1994 towards 01h45, a couple in the car observes
a luminous circle turning on itself and the edge of which
lights are evenly laid out. The supposed altitude [height]
of the phenomenon is 5 to 6 meters and the phenomenon
is stationary above the car. The car leaves the city quickly
but a little further, finds the phenomenon in front of
the vehicle: a triangle with the same type of light on
the circumference came to be added to the circle. The
triangle is equilateral 10 side meters approximately and
altitude from 10 to 15 meters. The phenomenon accompanied
the vehicle which ran to approximately 80 km/h while adapting
at the speed and that on several km. During a change of
direction, the object accelerated and moved away; the
witnesses then specified that it had the shape of a boomerang.
In the same time frame, and on the same road, another
couple in another car describes the phenomenon with a
similarity of terms completely surprising and described
the same evolutions compared to the vehicle. This phenomenon
could not be explained.
