This occured in the B25 after I had landed and occupied the dorsal gunner position.
The pilot head and elevator and rudder control surfaces were going crazy (I wasn't touching my HOTAS, just the mouse to control the gunner).
It was a COOP mission, 4.13RC4.
The track can be found in this post in this thread:
