These aircraft are flown regularly from North Weald - didn't realise the collection had its own website.
They are definitely one of best things about flying into that wonderful airfield. On more than one occasion I've called for join and been cautioned against "jet provost and spitfire traffic" in the circuit which you don't get just anywhere...
Watching the XI Spitfire takeoff, Merlin engine at full chat, is a sight and sound to behold.
Wasn't aware they had two seaters though.
