but the thing with a replica is you wont know if it perferms the same as the original, and the only way to find out is to test the original to the limit, don't get me wrong, i'm all for replicas, i'm just saying you should dtill fly an original if you still have it, there's no point in keeping it on the ground.....................
and whilst i see your point with the tail gunner, if a lanc went down he had the best chance of getting out mid air, and the most dangerous possistion on an american bomber would be the ball turret (that's why i said you had to be specific, you couldn't just say "which bomber" because not all had every gun posistion) because they had a habbit of simply falling out for no reason, even if they hadn't been hit, they were small, cramp and uncomfortable and you would have to stay there for hours on end..............
