Two black helicopters were over this guys area and a UFO shoots past. Was this an alien UFO or was this a military drone following them? Thats the big question. There are no wings, it is disk shaped for sure. Sorry I had to put the video sideways, but they guy filmed it long ways, and I didn't want to edit it, but wanted to keep it original.

Eyewitness states:
I was recording with my iPhone some blackhawk helicopters flying over my house at t/p/o and was gust reviewing the video I realized it was in slow motion and saw an object move from the bottom right to the left a lot faster than the helicopters even though they were both in slow motion.Not sure if it could be a bird but you guys are the experts let me know what you think If I can't figure out how to attach it to this form I will email seperatly I am a retired New York City Police Officer living in West Texas.
