If we're raising questions about the RAF's heavy bomber fleet, was the mid upper turret really of any use?
Either have the H2S dome right under the bomb aimer position and a ventral turret (apparently that was the intended use and even built into the fuselage) or could it have been mounted in the mid upper position?
And as for the nose turret - why? Won't you have a 200+mph wind/rain/sleet/snow/hail/birds into your face it must also have had some effect on the bullets being fired forward....
If they were to have any real use, the guns needed to outrange the night fighters, or have some real stopping power for a one bullet "kill".
Seems we just gave the illusion of self defence at the expense of 3 extra "crew" that just sat in their turrets trying to penetrate the darkness.
That to me is the epitome of braveness, flying night after night with pop guns against cannons.....
