You have to ask why it was necessary to destroy all aircraft of a particular type when they became obsolete, rather than keeping just one example for a museum.
Back in the 1950s, the last surviving Westland Welkin lurked behind a hangar at RAF Merryfield - I wonder what became of it?
A shame that not one Hornet, one of the most graceful aircraft the RAF ever had, survived the termites and bulldozers.
