I'm missing a good deal of the significance of this subject. I myself have seen ball lightning at least three times- one of the times it was large, having squeezed through a half open window during a lightning storm and then dropped to about knee high to me as it drifted out the open door. That one was orange. Another time it was a white, cloudy orb (indoors); another time there were two of them and they were blue and orange (outdoors, at twilight).

Speaking of the phenomenon as if it might have been intelligent smacks too much of black helicopters to me.
