3 white circular objects flying closely togetherSighting happened June 6th, 2008 between 6:00-6:30pm. I was flying North to Portland, Oregon in commercial aircraft. It was perfectly clear outside, sunshine, and not a cloud in the sky. As I was looking down outside at the beautiful mountains and green forest below I saw what appeared to be 3 circular white objects flying very close together in a perfect formation below the aircraft traveling very fast in the opposite direction. They must have been 10,000 to 20,000 feet below the aircraft so they looked very small. Each object was positioned a little ahead of the other in a perfect formation flying at the same speed.((NUFORC Note: We spoke with this witness, and found her to be an exceptionally capable witness.
