It's listed as being one of the recon assets that has been most asked for by US units in the recent "unpleasantness" in the Iraq/Middle East area of operations.
Given that it was designed for high altitude recon, one of the favorite pranks in years past was to invite interceptor units - RAF Phantom units - to "intercept" them - at 55K,an altitude at which the Canberras excelled and could outfly them.
Taking off at 80% power (or less) is common, since it's easy to exceed the landing gear's speed limitations - on one engine.
An interesting long-lived airframe (basic design is older than the B-52)
No wonder the British aircraft industry went down the drain - the damn planes refuse to get obsolete!
