erm...
Not to sound too harsh...but its gotta be said. an ORDINARY degree??? the 3rd class honours is better than that. and somoeone with a 3rd class honours doesnt have a hope in hell getting a job in aerospace with it!! I have several friends who got 2:2 (hons) in various Engineering degrees (aero, systems, mechanical..u name it!) who are REALLY struggling to get places...if u wanna work in maintainence, then scrap the whole degree thing alltogether...as you dont need it. get started on the B1/B2 thing with an HND.
