Yep, you can still see the tunnel I was working in on the southerly of the two old RAE Bedford sites. A 450,000 cu.ft pressurised wind tunnel in which I spent many happy hours running a stainless steel 1:18 scale Eurofighter up to about 2.5 Mach in what I think was an 8'x8' section - biggest such beast in Europe.
Yet another marvellous British asset decommissioned by short sighted beancounters. So what if it burned 70MW, we had our own set of pylons from the power station and it allowed us to generate test data that couldn't be produced anywhere else in Europe.
