I saw a formation of ufo's once. Yes, a formation in a v shape. Then I figured it out..... the time of day was sunset (orangey light) and the objects had to have been geese, so high up I could not hear their distinctive honking yet they caught the light just right to reflect the color of the sunset. and it was really hazy too, so all I really saw was football shapes with wings. No flapping motion detectable though... just too high up I suppose. It really threw me for a minute. Geese yeah.... that's my story and I am sticking to it.
