Lights? Human aircraft have lights for a reason ... for safety, movement on runways, and to aid with tracking among others. If alien ... why lights, and why lights in our visible spectrum? Aircraft lights are placed at extremal positions to help work out the approximate size and extent of the wings, tail, nose. They are not decorated with lights like a Christmas tree.

I checked reports on linked site ... triangular shapes and lights are a common theme. It seems both vaguely human designed to be seen without function just the kind of ambiguity that doesnt help. I remain skeptical.
