That accident was a consequence of the aircraft being pitched up too hard after a high speed (supersonic) dive, causing the aircraft to disintegrate in mid-air.
Not so! The accident was caused because the wing had only 64% of the ultimate strength required in the design due to an erroneous estimate of the allowable stress at that point. The intended manoeuvre would not have caused a catastrophic failure had the wing design not been faulty.
John Derry was subsequently absolved of any blame for the accident.
Nevertheless, pre-1952 Fanrborough was something of a free for all. However, by 1953 the Farnborough Airfield Commandant had wisely introduced a new set of rigidly enforced safety rules.
