As an aside, after ETPS moved out, those buildings became SETC - the (RAE) Student Engineers Training Centre; it gave I and quite a few others a great start to our working lives in aeronautics - but after SETC was shut down in the early 1990s (apparently MoD / DRA/ DERA / Qinetiq decided that the year of intensive engineering training we got there was no longer a useful and necessary add-on to a university degree. Frankly I think that they were wrong!) those buildings had been looking incredibly sorry for themselves, so it was probably inevitable.
However, at least the "Farnborough" quality brand still has a strong present and future and I'm sure will long outlast Qinetiq/TAG just as it already has HMBF, RAF, Min.Av, Min.tech, RAE....
As for ETPS, please not QTPS!, but if we ever have to admit that the Empire is gone, maybe RTPS wouldn't be too bad? I'm pretty sure that we're still a monarchy at least.
