Hi low, there are a few routes to being one of the few. It depends on your experience, but if youve flown in the RAF, or have lots of aerobatic experience it helps. if you go to
www.flyer.co.uk and have a look at the general discussion forum, I posted exactly the same question a few days ago with some very usefull answers.
Id be interested to hear what you think, I want to get into warbirds in a big way!
Regards, and long may the sound of the Merlin reign....
