niknak has really summed everything I've been thinking about over each career path. For a long time I was set on becoming a pilot, but thanks to many honest pilots, many on here and many in some of the best positions, and have gradually made me see the truth behind it all.
Saying piloting and controlling was a 50/50 split would be lieing, it was more 60/40 and piloting in the favour but the tables have turned, and after some hard thinking and questioning, I think controller is first option in my mind, but by no means because I see it as an easier way into the industry.
I doubt many controllers sit envying the guys at the other end of the mike, and whether vice versa.
I agree with spud, I know of failed ATCOs who are now airline pilots, but not the other way around.
