Big Green light took off at high rate of speed for a short distance then disappeared completely and turned red color right b4 disappearSaw a green light in the sky over the BW parkway Northbound before approaching Cheverly exit. It may have been still when I first saw it but I cant remember for sure. It suddenly took off and moved a short distance at a very high speed and completely disappeared. I believe I saw red light right before it completely vanished. I didn't see individual lights as you would for a plane. I saw a big green light that moved at a superfast speed before disappearing and possibly had red right before the disappearance. Never seen anything like this in my life and it sent chills throughout my body.
