[Paul Thompson 'Hooligan']

Interesting thread and I would think that the percentage will be much higher than simple calculation would dictate.

A 40 replica is not the cheapest of automotive hobbies, therefore it follows that many (not all) owners would fall into the category of having above average disposable income for 'fun activities'. Clearly pilots often (again not always) fall into this category and also i'm sure that many others, who are not pilots by profession, are able to indulge themselves with not just cars, but planes too - and why not! - I probably would given the chance...

Have I held a licence? - alas NO, but I have flown 'hands on':
A Comet
A Varsity
A chipmunk
A glider
and a Sepcat Jaguar - All (bar the glider) complements of my time in the Royal Aircraft Establishment (as was)... - oh happy days...

Oh - and my guess would be at least 10 times the expected percentage - or more. So between 2 - 5% of membership.
