Walking with a friend through Bramley Bank nature reserve with a friend tonight I said "listen!" She heard and looked me enquiringly. Not one but I reckon two Spits getting airborne from Biggin - the Airvan was up too. I could only see TE308 around a while later but the glorious sound was beautifully loud and certainly out of synch like only a pair of Merlins can be - not a Lycoming as well and the Airvan was well south of the airfield. Bloody marvellous! She, lucky girl, has had a look round the BHHH facility...
