It won't stop now, you have whats called the 'bug!' Hope your wallet is nice and fat, cos if you're anything like me, as soon as the money comes in, out it goes to my flying school (Newcastle Aero Club)
I remember my first-WOW!, i have a block coming up in a few weeks but really, still studying at school, i cannout get enough money in to knuckle down and do the whole PPL. I do read T.Thom books though, to get the theory in so it will be easier when the exams come around!
