On Friday the 13th I was returning about 7:30 pm. Driving east on Cape Coral Pkwy near 4 Freedoms Park. Six lanes of traffic; quite busy I had to pay attention to driving. I saw ahead to my left in the sky what I assumed was a commercial plane flying toward the Fort Myers International airport but when I seemed to pass it, glancing , I noticed it had a line up of red, green and yellow lights along the full side. It was NOT moving as I had to quickly glance back to see it. When I was finally able to move to a side street, stopping and looking back, it had vanished. It was growing dark and the sky was partially cloudy, the vehicle being below the cloud line. I heard no noise, and when thinking back realized it seemed small for a large jet to be that close. I repeat, it did not move either as a jet would have been far forward of the traffic and I would not have had to look back to see it. I knew it must be a UFO by the colored lights that ran the full length. I am not good at describing distances and as I was driving did not think of it. I am a MUFON member and am trying to be more careful of such observations. NOTE: The above image is a rendering.
