I have 290 hours; by early next year I hope to have the hours and the money to do the instructors course. One of my favourite occupations is taking people helicopter flying for the first time - and getting the "wow" factor back again myself through seeing them experience it. I love it when they ask questions too - even apparently simple ones that I then realise are extraordinarily hard to answer. I really enjoy it - and the idea of being paid to do that....
Will I still feel that way after the umpteenth trial lesson? Who knows, but it seems worth a try.
