Karnak:
Still haven't found gun arch diagrams for the Lancaster?
As I said, I only have the diagrams for one aircraft. I posted it so as to provide an example to you of what we needed you to provide to support your claim that the Lanc's arcs were too large. It is for you to support your claim, not me.

England's Radar and 50 miles of water and fighting over friendly territory advantage.
Sorry, no. There are reasons, valid ones, but that is not it. P-47s and P-51s faced the same against Germany, but were successful escorts because they could engage Bf109s and Fw190s from a qualitative parity, whereas the Bf110C-4 was at a disadvantage against both the Hurricane and Spitfire. This isn't to say the Bf110 wasn't a useful type, or that it didn't have successes against Hurricanes and Spitfires, just that the fight favored the Bf110's opponents. Goering's close escort order that came down during the battle exacerbated an already bad situation.
How did England's 'Defiant' interceptor work out?
Guns: 4 × 0.303 in (7.7 mm) Browning machine guns in hydraulically-powered dorsal turret (600 rpg)
No forward firing guns. <---- 110 way better
Yes, the Bf110 is vastly superior to the Defiant. The Defiant saw some initial success due to misidentification and later as a night fighter against bombers, but has to be considered one of the most disastrous aircraft programs of WWII.
So lanc's had no escorts because... spits were very short ranged. Too bad England didn't have 110's!
Bf109s and Fw190s are both significantly superior to Bf110s, hence Bf110s in RAF service would not have been successful trying to escort Lancasters into German airspace during the day.
Late in the war Mosquitoes were sometimes used as escorts for Lancasters during daylight operations, but I don't see that as a valid test of the Mosquito's capability as an escort as the Luftwaffe was a ragged shell of its former self by that time.
