I always wanted to become a military pilot rather than a civi pilot as a child. Almost every male in my fathers side joined the armed forces, mostly the same regiment as well (Scots Guards).
Although over the next couple of years it will be the civi route for me.
I am addicted to flying these days and yes I enjoy looking up in the sky for every passing aircraft.
I sometimes randomly drive down to the airport and just sit about watching the aircraft depart/arrive just for the fun of it, pretty sad to some but I really don't care.
