So, my guess would be that our government is paying these guys to put on a show once a year in Vegas just to keep the UFO believers in check.
Kind of strange if you ask me. I've seen something to the effect of a ufo myself across the field from my house when I was about 13.
It started out as a slow moving flying vehicle with white and orange flashing lights (slightly dim flashing, more like glowing and flashing).
It moved slowly strait down to the field and stopped, then hovered to another area in the field (all in straight lines and slow movement).
I'm watching TV at this time and just thought it might be a helicopter looking for an escaped criminal from a nearby prison.
When I glance out again this ufo now has one dim orange light and shoots towards my neighbors house at a blinding speed and disappears.
(without any noise mind you)
OK, now I'm thinking this can't be a man-made aircraft, because that was just too fast for our technology in 1974.
I went to the neighbors house the next morning and asked them if they saw this orange glow come towards there house (after explaining what I saw the previous night).
They said they did see this big orange light shoot through (or what seemed going through) their apple orchard right at their house and then it went vertical and disappeared.
Explain that one ufo-non-believers...
