Report from MUFON:
Date of event: May 14, 2010
Location of event: Salem, Oregon
"I was driving from Eugene to Portland on I-5, and was just south of Salem when I noticed a bright light in the sky. I assumed it was a planet at first, but then I realized it appeared larger as I continued to drive in its direction. As far as I could tell it was not moving. As I got closer, it appeared to be a glowing, white sphere that was hovering completely still directly above the freeway.
I soon saw 2 more in the distance, one of which was visible to the west until I was almost in Portland. A few miles after the first white one, I saw a dimmer, red sphere with a smaller flashing red light on one side. Then in the distance I saw what I thought was an airplane, but as I got closer I realized it wasn't moving either.
I saw two red lights and one green one. The green one slowly disappeared, and I realized the object appeared to be rotating very slowly.
I know that the McMinnville UFO Festival is going on right now, so I wondered if this had anything to do with that, but these seemed to be quite large and high in the sky, not something an amateur prankster could pull off. I haven't been able to find any mention of any aircraft or any other floating or flying objects around Salem tonight in the news or on Twitter. Hundreds of people must have seen them.
They were very clearly visible from the road. Does anyone know what they were?"
