A friend called me while on the road to tell me about bright lights in the sky that hovered, then dissapeared rapidly.

A friend called me on his cell while he was driving on rt 287 in NJ. He said he saw stationary multicolored blinking lights in the sky for a few seconds, then they moved off at a great speed, leaving a tracer. Since my friend has about ZERO imagination, I believe he saw something strange. We talked about the possibility of it being a UFO and I jokingly asked if he wanted to report it. He said HE didn't want to, because someone might come to talk to him and think he was nuts. But he told me it was okay if I knew how to. As I said before, this friend has a sci-fi value of zero, so i believe him that he saw SOMEthing odd. We live near many airports, and there's no way he'd call and say something if he thought it was even possibly an aircraft.
 P.S. He called me because of my flight experience and military backround.
