For a better idea of what at least some UFOs may be, Lynn Kitei's "Phoenix Lights" and Jacque Valee's "Magonia" are probably far more accurate than "material" explanations, at least in part.

I've seen one of the "orange discs" at night. They emit light that doesn't reflect off of surrounding surfaces, and their light appears "bioluminescent".
