Three lights surrounded by smokeI was driving along I-795 North. Initally I saw two lights surrounded by a large amount of smoke...at first I thought it was a traffic helicopter having problems. As I continued to watch - the lights seemed to rotate. Next I saw three lights in a straight line and the smoke disappeared as the lights took off - about the speed of a commercial jet. I pulled over and watched the lights move high into the sky (what I would say was higher than a commercial aircraft flying pattern in our area) and south until didn't see them anymore. I had about 5-7 mile visibility from where I pulled over. I didn't hear any noise, and I would estimate the lights were about 1/4 mile away from me and maybe the equivalent of 10-15 floors (as compared to a building) off the ground.
