Hi all. Just doing some historical research and have gone down a rabbit hole. I believe the only guns fitted to the Hudsons used by the Special Duties squadrons (161 and 138) were in the turret. Could these fire downwards to the rear and sides to any degree in level flight, or would the aircraft have to bank? If anyone can point me to detailed information on the fitout of these SD aircraft or the experience of flying in them as crew, I'd be most grateful.
