FWIW I think that Bruntingthorpe have got it right already; on a good weather day there is a sight to behold and I am sure there is room for even more by way of historical flyers. I was there one day when a Corsair pitched up out of the blue and made a very good impromptu airshow. Flying the beast is financial suicide even though it would be awesome, but that aeroplane IS still alive and available for all to see. I bet the driver pushes his luck at times getting "light on the wheels", I know I would!!
