This is probably an irrelevant comparison, and to an extent its not supposed to be, but why was it about the TSR2 that resulted in it being so comprehensively scrapped and almost deleted from existance? Was there a need to hide something? Were we so sure that the R&D and work that went into it was irrelevant and would never be needed?
Did we comprehensively dismantle the AEW3's in the same way as we appear to be doing here? I do recall seeing airframes sitting on airfields many many years after the programme died, and arguably it was in a less fit state than the MRA4?
