The following exert is an eye witness statement. Please read into it what you will. This has been reported to mufon who I am sure are investigating:
Traveling north on i-15 between mile 120 and 121 near manderfield utah. looking nw, near granite peak, three bright lights in a tight triangle shape clearly observed. lights hovered for approximately 3-4 seconds while i was looking at it â€” at this time, two other aircraft at a higher elevation and quite a distance away were also observed. (not a commercial aircraft area; but these two were clearly planes). the three tight triangle lights then appeared to â€œfallâ€� rapidly to a diagonal, still remaining in the nw sky, but quickly losing elevation. after approximately 4 seconds of falling, the lights all completely disappeared.
