Witness Account

I'm a UPS driver that drives from Albuquerque to cuba nm. On hwy 550 at 8:01am i saw a white craft lower than the clouds on the southwest side of the hwy at mile marker 28. I didn't think to much about it at first. I do see a lot of planes on this route but what made me pay attention is when it went from a almost hover to a high speed acceleration without a gradual speed up it was instant. It did change direction at some point and cross over the hwy in a northeast direction over the Jemez mountains. Last seen around mile marker 39. Heading towards Los Alamos. The craft looked as big as a military jet, white with two bumps. The smaller bump was the front. I could not see any wings or lights but it was about a good 4 miles away.
