If someone has a recording of the Wily Oriental Genleman's tirade and there are witnesses to the public dismissal of the cadet, there could be strong legal grounds for a lawsuit. If all the cadets pulled the plug simultaneously, mounted a class action for non-delivery of the goods, intimidation etc etc there could be some money to be made here. Maybe even enough for each to then fund a licence course independently and not be beholden to these bottom feeders of aviation.
