Well the TSR2 is an entirely different story which I'm also having to follow at the moment in connection with another publishing project. Like the M.52, it has a lot of sentimentality and urban myth attached to it. My own view (which I'm happy to change in the light of any evidence!) is that both the M.52 and TSR2 projects were both simple victims of cost, pure and simple. I don't buy into the notion that there were any dark political reasons which caused either aircraft to be cancelled even though such reasons have been perpetuated for decades. When you look at hard facts (such as they are) you tend to get a different story to the one that gets churned out again and again. I suppose it's just a symptom of human nature that people try and make stories appear more interesting than they actually are, but I've seen no evidence to suggest that either TSR2 or the M.52 were anything other than victims of their own cost.
