The subject of silver egg shaped ufo drew me to this posted discussion.
I actually did see one of these myself while driving.
I am a middle school art teacher, and it was the first day of school. I was driving home and passed a local high school where the entire parking was filled with yellow school buses. My first thought was, "Wow, that's a lot of yellow." Just as I reached the lot full of buses, I noticed a stream of sparks emitting downward from a power line which crossed over the road on which I was driving. It was a bit frightening, and I hit my brakes just before driving under the sparks. Looking up, moving away in a right diagonal upward direction, and away from the sparking area on the power line. I saw a silver egg-shaped object.
Why include the part about the yellow buses? Well, it was just part of the sequence before seeing the silver oval moving away from the sparking power line.
Afterwards, I thought the yellow buses must have created quite a bright sign when viewed from the sky. Also they were parked neatly in what would have been a herringbone pattern from the aerial view.
