This was one of the most successful of the great postwar blossoming of the aircraft industry, producing such aircraft as the Hawker Hunter, the Lightning, and the V bombers.
The Canberra was designed to fill the same niche as the wartime Mosquito - fast, and yet with a reasonable payload or reconnaisance capability. It was sold to many other countries, and was used, but without much success, by the Argentinians in the Falkland conflict.
In its early days, it set up many records for long distance flight. It has been said of an aircraft, that if it looks right, then it probably flies right. And the Canberra was a very elegant aircraft.
Four photo reconnaissance Canberras were still in active service in the Middle East in 2003 - which speaks volumes for its design!
