Someone just made something that was done several thousand times in the past unnecessarily complicated by trying to add the abomination bastard offspring of a private financing deal called RAF Voyager into the picture. Without real need to do so.
That is on internal fuel with no drop tanks by the way. With drop tanks it should be able to skip the Faroe and maybe Greenland with a stop just in Iceland on the way. By the way its range on internal/external is nearly identical to the P51 Mustang out of which 4K+ flew down this route with the exact same stops in WW2.
