Me and my friend were driving from Flagstaff to Phoenix and saw a UFO. It was brighter and bigger than a star and was hovering for a bit, changed direction, then it went down towards the treetops in the forest. It did not look like a meteorite because it had no tail. It was a bright yellow/white color. The event lasted for approximately 3-5 seconds. We don't know where or if it landed. We were very curious to know exactly what it was and a bit shocked.
