I was driving to repton to drop off my daughter's boyfriend after he had been over for the day so all three of us were in the car. when we got to repton road by foremark reservoir we all noticed a bright orange light coming through the tress by the side of the road. it was so bright it looked almost like it was the sun at sunrise or sunset. it was night time so we were very surprised to see such a weird light. i slowed the car down and as we got near the light got brighter and then we saw that it was a large orange ball that was glowing. the ball hovered in the trees for a second and then flew over the top of my car at great speed. i have a panaramic sunroof so as it went overhead the whole car lit up like it was daylight. the light made no noise at all as it went overhead and the car stalled while it was above us. all of our mobile phones starting vibrating as the light flew past and the car would not start again. after a few seconds the light had already flown over a nearby hill out of sight. about 30 seconds later the car started again and then we heard a helicopter. my daughters boyfriend got out of the car to get a better view and there were three helicopters with no visible lights flying over head in the direction that the bright light had flown. once he got back in the car we got out of there as quick as we could.
