Aeronautical engineer...
Just want to point out something about the loans, which i am looking into atm to fund my training.
Your job/degree affects how much loan you can take out. Even though the loans available are a straight equity exchange on your parents home, if you dont have a high earning potential or your parents dont have enough disposable income to pay the loan payments you may be refused on the loan or be offered a lower amount to what you requested.
So i would bare that in mind when you look towards a secondary career.
