Failure occurs during a mission that I am writing and at a predictable point in the mission after a bombing run. It does NOT occur if you bypass the bombing run. Any help or reference are appreciated. Thanks.

Jake, maybe you need to ask the FSX forum. I'm not sure what a bombing run mission and the MD11 have in common?
