Very nice skin, Greebo.
They did do daylight raids, and suffered heavy casualties when met by the Luftwaffe, flying in spread out formations.
Since AH decided to equip Lancasters with .50 cal, they do damage. Ive seen one Lancaster with .30 ever in AH.
Its pretty much like LA-7 with 3 guns, existed i very low percentage, and used to 100% in-game.
IRL .30 did little to harm the heavy fighters of the Luftwaffe.
While we don't have the Tallboy bomb or modified Lancasters that carried them, the Tirpitz was attacked in Norway during the daylight as well as other "precision" attacks in France after D-Day. While not often, they were used during the daylight especially later in the war after air superiority had been won by the Allies.
