It's quite sobering to think that the Jet Age has lasted far longer than the period between the Wright brothers' first wobbly flight and the first jets in the 1940s. For most people alive today, jet travel is all they've known. Supersonic commercial flights have come and gone with Concorde, and flying at 600 knots for the masses has become a humdrum part of travel.
Back to Canberras. When I was in the RAF in the 70s, Canberras were thought of as quite old even then, many in storage and used for parts for the dwindling number still flying. The U.S. had their own licence built variant, so I suppose the sheer numbers built would make it more likely that there would be some survivors still today. Its distinctive shape makes it instantly recognisable, quite iconic really, particularly the PR9 with its offset cockpit canopy.
