Long blimp like shaped ufo

I was standing in a friend's yard with Their neighbor, the sky was mostly clear only a few scattered clouds, it was around 8:30pm, when I was just looking at the sky listening to friends conversations hanging out, and all of a sudden myself and the neighbor see a long blimp like shaped object appear moving at a pretty slow speed, it had lights all across the side of it of all different colors, then it speeds up and all of a sudden it takes off so fast and moving in a way unlike anything I have ever seen before.  This was not a plane, not a blimp, nothing known on earth moves the way this craft moved!
