About 95% of UFOs are unidentified naturally occurring phenomena with which we have little experience or understanding. The remaining 4.9% are angelic or demonic beings coming and going with the smallest share remaining being some sort of extraterrestrial craft.
As I have said before, Myself, wife, and several friends witnessed a YUGE UFO here in Ithaca. Hundreds probably thousands of other people saw it.
An employee of mine was at the mall and saw it along with everyone else at the mall. It was reported on Binghamton TV news.
It was never identified. Some thought it was a blimp, but the news even said that there were no blimps in the area.
It was YUGE!, appeared relatively low, moved slowly, made no sound. Many lights all in triangular formation. At first I thought it was many vehicles, but then they (it) all rotated in unison making it clear that it was a single large vehicle.
