Nothing man made can be so big and fly so slow,make no sound and make night into day.Driving home after work at about 23:15. The night was clear and the road was deserted except for me and a car about 20 meters behind me. Suddenly the sky was filled with a bright light, I braked hard from my surpize and looked up. I saw two round objects which seemed quite large flying VERY slowly (one slightly behind the other). They made no sound.What amased me was how slowly they flew and the amount of light they made. The "flying objects" were travelling from east to west. The other driver also stopped and was amazed at what he had also seen.
