Yes the 'fishbowl' canopy was a silly idea,we really should have had our own version of the B57 type canopy,of course the PR9/BI 8 were ok for the pilots !
Based on my ONE flight in a T4 with a 'Trapper' on 231 OCU in 1974ish - very smooth and quiet ,very pleasant to fly and others much more qualified to post will confirm that assymetric flying was its achilles heel.
The Canberras without Cold Air Units were very uncomfortable for the aircrew at low level,summer of '76 was not nice for the B2 drivers.
