[Poohbah]

After a falling out over intellectual capital, it appears that Cooper changed his story. He was able to host a radio show and in addition to his renewed faith in Jesus, he sought to clear his "misunderstanding" about alien conspiracy.

Updated account from someone who saw the infamous Lear-Cooper falling-out as it happened:

Actually, he U-turned about the aliens after William Lear and another "ufologist" made up some stuff on an alien being named "O.H. Krill," and were about to announce it on TV with Cooper there, and Bill Cooper said, "Yes, it was in all those documents I read at CINCPACFLT headquarters." Lear yanked Cooper aside and said, "Bill, this is a JOKE!"

Cooper got hostile and INSISTED that Krill wasn't a joke. Destroyed his own credibility right then and there.
