English Electric Canberra
Entering service with the RAF in the early 1950s, the Canberra was developed as a high altitude light bomber and set a new world altitude record in 1957. Almost 800 served with the Royal Air Force, and it was exported to almost 20 other countries. In the US, it was licensed built by the Glenn L Martin company who built 400 for the USAF.
The RAF continued to operate the Canberra in its photographic reconnaissance role until 2007. Until its retirement, its unique capabilities were in great demand and were shrouded in secrecy.
NASA currently operate two WB-57Fs from Houston, Tx, these examples having extended wings for high altitude flights.
