If any body is interested the CAA have changed the rules on warbird flying, from Feb 2015 you can pay for a passenger flight in one.eg spitfire. At a price. google www intotheblue.co.uk for prices. no personal connection.
And about time too!
As well as
IntoTheBlue at Biggin Hill there is also
The Boultbee Flight Academy operating out of Goodwood.
The going rate for both seems to be £2750.
Boultbee has been petitioning for years to get the rules change so it's great that finally we'll be able to ride in a Spit without having to go to South Africa first.
