I was on vacation. I was staying at Caesars Palace in Las Vegas. I went outside by the pool to relax. What I saw above me was spectacular. I have it on video. four ufos flying above while a small white object way above to the south of the flying objects was hovering in a vibrating pulsating motion. The UFOS' look as though they were fighting. They turn their jets on and off. In the meantime, there were at least 50 helicopters that I saw flying about 100 feet above me as though they knew something was either going on for wrong about the look as though they were fighting.

This was something I had never never seen before. I was shaking up for a few days and as a team to report it but I think it's important.
