 In fact the bomber had a span 2 m (6 ft 7 in) greater and larger wing area.The fuselage behind the wing leading edge was again similar; as far as is known the defensive armament intended for the bomber was never fitted, and it had three windows on each side, though not the continuous line of sliding openings seen on the transport.The main differences were in the pilot's cockpit and those that followed from a different choice of engine.
