There was a post here about a thread regarding this subject on another forum, and I thought it might be fun to start one here. I'll start with mine:
Castle Air Museums B-29 "Raz'n H*ll". This B-29 is made up of three different B-29's (wings, fuselage, tail section). The tail section belonged to the true "Razin' H*ll". While assembling it, a cloth name tag was found in the tail section. It had one name on it, "Arthur". That's what we call our resident spook.
There have been many reports of odd occurrences. I know many people who have experienced it, myself included. Amongst the stories told to me:
A person was working in the plane, and another handing tools to him. The guy working was reaching back for tools, not looking. When he finished he turned around only to see no one was there. He looked out of the window, and saw his partner sitting on a bench outside.
We have been called by local law enforcement telling us we left the lights on in the airplane. Needless to say, there are no lights.

We have found props turned in the morning. As you all know, those props don't move by hand or high wind.
Our volunteer coordinator has a picture behind her desk (that she took) of a "smokey" outline of a person in the cockpit.
And many more.
My experiences:
One night I was out there due to a function. I went over to show the B-29 to my wife. The museum was closed, empty, deserted, etc. It was about midnight. As we walked towards the plane, I heard the unmistakeable sound of radio chatter. I turned to ask my wife if she had heard it, but she was already beating feet back to the car! LoL
Whilst showing the plane to some visitors, and telling them about Arthur, an outside cockpit latch started to open and close itself repeatedly. Everyone got a goose-pimple.
It has also been documented in a couple "Ghost Hunter" type shows.
That's it, Next!
