Thank goodness their flying lives were short like the Halifax /Halton they were wildly expensive to fly and let's face were meant to be bombers, hoisted onto the airlines as there were no Dollars to buy commercial aircraft from America our aircraft industry were still suffering from lack of funding , and trying to go over to civilian planes even the Viking was a Wellington shape with a stressed ally body with fabric wings until the mark 1a was developed but a lot of it was Wimpy even that had the spar running through the cabin , the up side was business men used to scramble to certain seats to catch a glimpse of a stocking top plus suspender as the stewardess stepped over them . Sorry about the Drift back to the fatalities, wrong aircraft ,lack of flying aids ,poor autopilot only good for straight and level, increase of pilot fatigue, bad weather.
