You're not too old, you have clearly given this a lot of thought, there is a pilot shortage looming, you have a career you can fall back on if this goes wrong. You've played a good hand so far. I know nothing about the school you speak of, being globally mobile is definitely an asset. Do it before you walk into a tree or lamppost and hurt your self. Life's too short, get on with it. There are plenty of people on here who have had a tough year or so and many victims of the negative elements of the business. That doesn't make it a bad business but it does have it's challenges.
