From the Letters page Manchester Metro News 29 Sep
"With reference to your article regarding the sad passing of Avro test pilot Ken Cook I feel the content was not quite accurate. Ken was an excellent test pilot who later retired from flying to become Senior Air Traffic Controller for the Company. However, he certainly was not the very last Avro test pilot as Jimmy Harrison, Tony Walker, Tony Blackman and a number of others are still around. Harry Holmes Avro historian."
I understand the original article was written by a 'freelance' journalist. Presumably he is now back to reporting aviation disasters or Party conferences!
