I’d say go into Engineering.
If you can get into the stress/design side of gas turbines or aerostructures it’ll give you a unique insight into the things you’ll eventually be flying. Plus, with a bit of experience you’ll always be in demand (there is definitely a shortage of good, experienced engineers in the aerospace business). The pay is reasonable without being spectacular (unless you are a contract engineer, but that takes special skills).
My family is full of teachers all moaning about their loss of control in the profession and red tape, red tape, bureaucracy, and more red tape.
Your choice, you don’t have to listen to me. Oh, what do I do? I’m a contract aerospace stress engineer currently working on A380 components who has a frozen ATPL, waiting for a chance to fly for a living……
