I WAS around at the time of the cancellation and fumed about it mightily. However, at that time I hadn't been exposed to the excruciating activities of the 555 committees and the ability of the P E to modify a basically good design into a 'dog'. It may well have been that TSR2 could have withstood such inputs but we'll never know.
What I did note at the time was the frequent correspondence from one particular reader in 'Flight' magazine decrying the aircraft and its concept. These letters naturally ceased at the time of cancellation and, as far as I know, the particular gentleman has never ventured into aviation correspondence since.
"Curiouser and curiouser", said Alice.
