I worked at PKI on the Tower in the early and mid 90's. As you can imagine, spending 10 hours a day all summer on the tower lent itself to experiencing some pretty wierd things. I have several stories which I could share. I was usually not alone and others can attest to many unexplained happenings while working during these years.
Although, I can't remember a time when Johnny would reveal himself in a way that guests would be aware of him, he certainly wanted the crew to know he was around. His favorite tricks were closing/opening the elevator doors. Sending elevators up/down on their own. Elevators stopping during transit, signal 2-9's(?). (Yes, this all happened!) Mostly just the ride performing operations that no one instructed it to and no explanation-even from maintenance.
This could have been electrical problems with the el's themselves...lightning would strike, system glitch, etc.
But the Tower Johnny explanation is sooo much sexier...!
