Those who supported TSR-2 should have observed events at Avro Canada before 20th February 1959 ("Black Friday").
The remarks attributed to Sir Sydney Camm that ALL aircraft possess four features, span, length, height and politics and that TSR-2 simply got the first three right could equally have applied to the Avro Arrow.
The "winner" of the TSR-2 fiasco was of course the Blackburn Buccaneer.
