The 'Car door' caused some problems for pilots bailing-out, being a cramped situation with all the clobber on, especially if hit when diving, as their dive speed was 600 mph... Pulling-out was a delicate affair anyway, too much throttle and they could stall... - It's a recorded 'relief' RAF pilots felt, when the bubble canopies came on line....
According to a Book called "Typhoon Attack" by Norman Franks, which I have just finished reading, Tiffy Squadrons were given 3 Seperate roles, these were Dive Bombing, Rocket Attack and Escort Fighter, and Tiffy Squadrons specialised in doing one of these jobs only, squadrons being allocated specific tasks dependant upon the training the pilots had received. although in situations like the Falaise Pocket, all the Tiffy Squadrons bombed, fired rockets and just generally shot up anything that they could find.
Apparently the Tiffy was also fitted with experimental Rocket Rails, which had 2 Tiers, so instead of 8 Rockets being carried, they could carry up to 16, these were soon dispensed with as they could set off the Rockets which were mounted above them.
