Gnat v Hawk
I think someone's missing the point slightly here. The Gnat was an excellent trainer for the operational aircraft of the time. It had similar flying qualities and vices to the Lightning, F4, Jaguar and Buccaneer. When the Tornado arrived it was much easier to fly. The dangerous period was when the Hawk was training pilots for the older jets. It just did not have the same swept-wing characteristics and meant that the OCU instructors had to spend more time teaching them on the operational aircraft.
