I thought it almost went without saying that if TSR2 had entered service, then Tornado would never have happened. That's obvious to anyone!
As for Beamont's comments, it's always worth remembering who he was and what his background was. Whilst I wouldn't argue with anything he said, it's worth taking some of his comments with a pinch of salt as he was speaking from a less-than neutral position in the whole saga.
Unfortunately there's a bit of an "Elvis Syndrome" associated with TSR2. The aircraft was undoubtedly a good one but it has been surrounded by urban myths, hype, conspiracy tales and other assorted rubbish for decades.
