Police escorted military vehicles with incredible UFO like vehicle being transported under the cover of darkness

Now let me start off by saying that this vehicle could very well be a secret military experimental aircraft. Here is my story and what I witnessed. I am a truck driver, I was on my way from San Bernardino CA to Las Vegas NV. It was around 11 pm on Thursday, February 9th, at that time I was in between Baker and Primm California heading north on I-15. After some time I had noticed that there wasn't any traffic heading south on I-15 for at least 5 minutes. I just figured that there must be an accident on the other side but a few minutes later as I was cresting a hill here comes the highway patrol with all their lights on driving somewhere between 80-100 mph with the military in tow. They were all escorting a single flatbed trailer with an incredible somewhat triangular shaped UFO like vehicle on the trailer. It was much wider than the trailer and had 3 sets of landing gear in which it stood upon. It was also covered in a shrink-wrap like material. It had markings on it but none looked familiar (no American flag or numbers that I could see). The color of the material it was covered in was light gray, dark gray and black. I desperately tried to get my phone out of the car dock to try and get a picture but wasn't fast enough. Behind the truck carrying the UFO was more military vehicles and then about a half mile or so behind them were more state troopers keeping traffic back. I've seen many different UFO pictures and this object was close to being similar to the TR-3 but it's edges were much more rounded and wider. I really wish I could have gotten a picture of it, but then again I'd probably have the military or some men in black paying me a visit. mufon cms# 82062
