I was driving home from work, and saw green lights hovering off the side of the road, about level with the top of power lines. I could see a dark silver metal, and 4-5 green lights, then one yellow at the bottom and two orange in the middle of the green and yellow lights. Then it lifted up and took off at a diagonal direction upwards very very fast. If I would have blinked, I'd have missed it. There were no sounds at all. No radio disturbances. No other visuals or cars on the road.
