On march 6th 2001. I was in the foothills area of Gillette Wyoming. I looked to the sky and saw a blue light gliding across the sky towards me. Seconds afterwards I seen the light morph It now had a blue, a red, a white light. Similar to a plane but this was no plane It flew over my head. It most of been only a mile high in the air. I could see the bottom of the ship. It was grey and triangular. It then traveled across town heading southwest. circled aroud some radio towers and disappeared to the west. It changed into a singular red flashing light that blinked every 3 seconds. Then it switched into a white light and dissappeared. The object made a low humming noise.((NUFORC Note: Witness indicates above date of March 06, 2001, but enters date of March 09, 2000 in box for date of alleged event.
