I was driving from pierrelatte north along the n7 to montelimar. i saw two cylindrical objects above the tree line on about the same level as the hill top village of la garde d'ademar. i noticed them because they were not moving and because they were cylindrical. also they were very large. larger than a plane (light aircraft). one object was higher than the other, and positioned slightly more to the south. it made me think of planes refuelling in mid-air. but these were not plane shaped objets and there was no connecting tube visible. as i drove, i could not see the slightest movement from either object. suddenly i went past a wooded area which shielded my view. this lasted about 30 seconds. when i was once again able to see past the trees, no objects were visible. i stopped the car another 30 seconds later when i came to a roundabout (i.E able to stop) and got out to have a good look, and see if i could see the objects were moving away in the distance. but nothing was visible at all. i was shocked to think it might have been a ufo. i certainly wasn't thinking about anything like that when driving. i checked the internet the next day to see if anything had been reported. a ufo sighting had been reporting for the previous week around pierrelatte, but not that day. fyi pierrelatte is the site of a nuclear power station (tricastin) and the largest plutonium recycling plant in france. there is another nuclear power station north of montelimar.
