I'm a skeptic, and I wonder if the process of eliminating and discrediting UFO events has enough categories. Do they take into consideration the testimony of pilots who may be experiencing sensory and or sleep deprivation, or even an amphetamine psychosis or something comparable?
And as far as witnesses on the ground, do they eliminate the "trance" events as described in GH's Supernatural? Or, of course, amphetamine psychosis, hallucinogenics, mental illnesses?

I don't believe UFO are extra. But I do realize that it is a massive phenomena that certainly deserves study. But I'm going to look for ways to poke holes in the theory.

I should add that I will probably never be convinced by video evidence.
