11-15-2012 orb sighted over Vancouver Washington areaWe were driving over the I-205 bridge by the Portland International Airport, heading south, about 8 PM There were several prominent lights in the sky, mostly to the West of the airport. Some were aircraft, some were orb shaped. There had been substantial contrail spraying about 4 PM over the West Hills and the front of the cloud bank had reached the Vancouver area. I mentally noted that and continued home to Portland, three miles from the airport. As I stood in my parking lot, three F-15 fighters were scrambled from Kulis AFB on afterburner. They formed up and flew over my head at pattern altitude, then headed towards the Vancouver mall. My view was blocked by a building. My friend that lives by the Vancouver mall reported seeing a large flash and heard a loud sonic boom about 9 pm.
