There were two distinct canopiy types for the Canberra - th4 "bomber" style bubble which was "normal" in location (although the pilot sat offset to the left and the navigator and bombardier were to the right and below him. When the interdiction (ground attack) version was designed it kept the pilot where he had been in the bomber version under a new "fighter" canopy. Bombers, trainers and most "utility" versions used the bomber canopy. The B(I) and later photo-recon versions used the fighter canopy.
