I was stand by a building on the old Wendover Airfeild. Southeast I noticed something moving in the sky. As I watch it moved from south east went over west wendover NV going toward Oregon. The point of the cross was close to the left tip making it look like a backwards y. Under it a strip the enitre length of the wing was something. Thier was no tail or wing lights. It was fly so low that my flash light could hit it. Which I did and that is when i saw the strip on it's belly/Wing. The sound was a low pitch hum. sort of oscillating but not load.
