Sounds like Express Air One. Their president came from a previous airline whose upper management had been under federal investigation, then turned state's evidence against his partner, some of whom did serious prison time and I believe a suicide or convenient death or two was involved as well. You are invited to guess whom the source of the original corrupt practices was, and who likely tipped off the feds as well....and well as to how the current airline he runs is managed.
The current operation is so far as I know, the only airline to have had an alleged stowaway/attempted hijacker ejected from a passenger airliner in flight.
