It certainly looks that way....not being a pilot, I don't know if that's normal or not for this sort of aircraft. Undoubtedly somebody will come along soon who can add information about that....Free Republic is teeming with experts on all manner of military and aviation subjects.
My understanding was the cockpit canopy was open in case of ejection at slow speed and low altitude.
Egress systems back then were not quick and if you attempted ejection at takeoff speeds, the canopy may not cleanly separate and/or may not separate fast enough, to prevent the pilot from going through the glass and possibly losing his kneecaps. That is what I seem to recall in Life Support school a few years back.
