Bright red light, waning until disappearing, moving in small, erratic, directional changes, and didn't seem to be acting as an aircraft.While sitting outside our home, we noticed a one very bright red flashing light that appeared to be moving in small increments in different directions. After approximately 20 minutes, the brightness of the object gradually waned to merely another light, similar to a "star" in the sky. Moments later, it literally disappeared. I am aware of different conditions that can seem odd to the casual observer, such as a jet airplane that may be cruising at high altitude after sunset and the Sun's rays reflecting off the airliner's skin and appearing to be a bright red fast moving object. I have been around airports and airplanes for most of life and have seen many aerial objects in combat areas, so I know something odd when I see it. I sincerely believe that I witnessed a UFO above the Mesa/Apache Junction/Queen Creek, Arizona area. Thank you.
