We spent a great afternoon at Biggin Hill recently with the Biggin Hill Heritage Hangar.  A really nice set up with a bunch of Spitfires a Hurricane and a Bf109.  The hangar is bright and airy and almost OCD clean with the aircraft accessible and plenty of history to absorb!  There are 3 /4 Spitfires being restored including two with great desert camouflage.  My brother in law was having a flight in MJ627 so the hangers-on took advantage of the hospitality and relaxed during the flight.
