aviation degrees are no use to man nor beast in any other industry.
I have to disagree. Sweeping statements like that help no one as you have not provided any supporting evidence for your obviously simplistic outlook on life (sorry to be so blunt).
As mentioned elsewhere above for a lot of good jobs it does not matter what degree you have, just having a degree (any degree) is required. Also if it has decent management content that can be applied anywhere.
Besides I know of a graduate from an aviation degree who is now earning a fortune as a paralegal advisor in aviation to a City law firm.
