Well, when you compare a legal career to an aviation career my own humble opinion is that law is simply the easier option (not saying that it is in any way easy in itself...).
It's also a numbers game - compare the £25,000 odd loan that you need to get to be a lawyer with the £60,000 that you need to end up in the RHS of a commercial plane. Plus job security in law is currently extremely good, with salaries to match.
That said..........I'd still rather be flying! Will have to wait until the end of my training contract to see whether I want to jack it in or not - but my inclination is that I'll end up sticking with the law and *hopefully* fly as much as possible in my spare time.
