The prototype BAC1-11 which crashed on Salisbury Plain due to a deep stall was being flown by Mike Lithgow, the then deputy chief test pilot of Vickers. Subsequently, the 1-11 was fitted with both hydraulically powered elevators and a stick push system. Lithgow was the pilot who flew the Swft to a short-lived world speed record of 735 mph in 1953.
The CAA pilot to whom you refer was perhaps D P Davies who was the Chief Airworthiness TP and was well known for the stick pusher requirements on such aircraft as the DC and B727. Davies was the author of the well-known book entitled 'Handling the Big Jets' which was/is the bible of aircraft behaviour for generations of multi-jet pilots.
Your remarks about the 1-11 and the UKCAA are both wrong in fact and a bit unfortunate in tone.
