I have a friend who works at Duxford Air Museum.
He tells me that the Renault F1 team are back at Duxford this Wednesday (weather dependant) doing testing runs up the runway - normal museum opening times 10am-6pm.
yet they have air displays there a number of times a year- and planes every day. I saw a Nimrod doing aerobatics there (as nearly as it could) and it made one of my children cry it was so loud.
I know! Some of those old planes make a hell of a noise. I saw a Vickers VC-10 landing and I swear it made more noise than Concorde taking off (which if you've never seen her, that was a seriously noisy experience)!!! Can't beat a bit of nice throaty noise though.
