8/5/2017 Update: Many people (including fellow researcher Kerry McClure, who learned of MUFON's investigation into this) have shared online that they suspect this plane passenger was viewing the light reflecting from a solar generating facility, as there are many so-called "solar farms" located in Nevada and California. Although the witness guessed they were flying over Arizona, they could very well have been flying over nearby Nevada or California realizing. Check out the solar farm locations and images from the Ivanpah Solar Power Facility below, and judge for yourself whether this explanation is good enough:
A clear daytime video showing three bright orbs of light hovering (or possibly sitting stationary on the ground or a mountain) being viewed by two witnesses through an airplane window has been uploaded to YouTube:
Strangely enough, TexasUFOs reported on a similar sighting that occurred not long after this one --- strange lights hovering near a plane over Houston --- but in that case, the lights vanished quickly:
Could these cases be related?
This is the first and only UFO video to be uploaded to this specific channel, and the supposed witness followed up with me with about the location they were traveling over. They were "going from Albuquerque, New Mexico to Oakland, California" and estimated they were probably flying over Northern Arizona at the time.
Pretty amazing footage! What do you think these airplane passengers witnessed? Could they just be viewing mundane building or ground lights from afar, seeing a strange reflection of sunlight, or could they be viewing something rather mysterious, perhaps even alien?
