Jean Boyer was driving home and reached the area of Pont-la-Dame and was ready to climb the stretch of road called Cote des Egaux.That's when I saw in the sky, right above Pont-la-Dame, in the valley of the Grand Buech river, a motionless & luminous disk.
I believe it was about 200' to 1,200' above the ground.
After 2 or 3 minutes, some sparks flew as the object rose vertically at a dizzying speed.
