I guess I was possibly born with a love of aircraft, and then really got the bug when my older brother took me to the local airport in the late 1950's, when I was around 7 years old. He was a member of the enthusiasts group there, and they were allowed access to the hangars, ramp and most areas, in the days when airport security didn't really exist.
Great to see the civil aircraft of the time, mainly Dakotas, Vikings and Ambassadors, with the odd "exotic" types, such as Viscounts, Constellations, Bristol Freighters, and maybe even a Britannia, alongside light aircraft such as Austers, Proctors, Tiger Moths and so on.
Even better was being able to get up close, and even be allowed access inside many of the aircraft, with the ultimate excitement being when I sat in the co-pilot's seat of a Dakota (an ex-RAF, WW2 veteran) and "helped" to taxi it.
