Lights in the Portland sky with up to six lights in the sky and then the front one in the formation would take off to the north of the sky. Three lights did this with one staying constant. Then black hawk helicopter landed on downtown Portland building "federal building" then took off with bright search light towards light. Then it was joined by another helicopter that gained altitude towards the light. Black hawk came back landed again on building and took off again. All of a sudden, lights reappeared in formation just to break up again. I do have video of this as well along with my brother's video.((NUFORC Note: We spoke via telephone with the witness, and he corrected the date. He sounded to us to be quite sincere about the alleged incident. PD))
