I would have to agree with Lucifer. The City firms are apparently very keen on taking on graduates from an engineering field - especially aero. Its for all the usual reasons, meeting deadlines with very high work-loads, logical thought processing, working with numbers etc. There's no reason why an aero eng degree or any other engineering related degree should retrict your career choice (to a certain extent of course). But whatever you do, dont do an eng. degree if you're not interested in it at all - it will drive you crazy!
