The Mossie also lacks the ability to slow down rapidly just by throttling back. You have to slam the rudder hard over to get as much fuselage into the wind as possible.
De Haviland was initially going to include a frill airbrake on the Mossie due to concerns from Fighter Command that it would not slow down fast enough to get good firing solutions. The frill airbrake was abandoned when it was found that lowering the landing gear had the same effect. This doesn't work in AH because the landing gear cannot be lowered at high speeds without ripping them off.
