Chris,
Just watched a documentary on the Avro Arrow. Yes it sure was a great aircraft that suffered the same fate as the TSR2 except the Canadians managed to hang on a bit longer
I saw Darryl Zanuck ??? doing aerobatics with the Arrow in Farnborough one year ( I am sure someone will tell me which - the memeries going!)
He did the tail slide which was considered impossible for Jet ( in those days)
Good documentary ( Discovery I think)
