s'land: ICM is right. In 1964 Shorts puffed (RB178, precursor of) RB211 on C-141 wings on Belfast's cube. The reason we bought neither that nor more with Tyne was that by then we realised we had overbought our needs...by 10.
fed: TSR.2 jigs, like all detritus in cancellations, were disposed of asap because the contractor has better things to do with the space than to maintain junk safely, while charging us for the pleasure. Junk. See the TSR.2 Cosford RAF Museum; look at the open avionics bay. Shudder. MTBF would have been measured in minutes. 1957 steam was the basis of the design; by 1965 we were onway to k-bytes.
