sighting of UFO

i dont have the tape but my brother was on his way back with my dad and my sister from las vegas. And he had a video camera with him, he cought something in the sky. I have seen the tape and it look's like to me a cell phone, the weird thing was is that it changed from blue, to red,to orange ect and then it disappearded. Any thoughts on what it might be?

the video to an mpg, avi? There are a couple on this board who are pretty good at analyzing video, etc.

from Las Vegas huh It might be a X-Craft or it just might be a UFO But I wouldent get your hopes up though
