Easy - I grew up with it. My dad passed his PPL when I was 4yrs old and I have some great early memeries from the many, many hrs I flew as pax... I remember poleing around a Rallye long before I could reach the rudder pedels.
Also, me and my brother thought it was great fun pulling the rudder cables when flying in the back of our Tri Pacer much to our chastisement from mum. 'Will you two stop messing around, daddy's trying to land!...'
We also used to take turns riding in a Cub with the doors open to fly over the strip and throw Action Man out on his parachute - very cool when you are six! As a strange quirk of fate - I'm now a co owner of that Strip and a Cub too nearly 30years later.
It took many years to get my PPL mainly due to women/money problems but I did loads of gliding and stuff which kept me flying in the mean time.
