 With this flurry of order and production having been assured by the end of 1937, Vickers set about simplifying the manufacturing process of the aircraft and announced a target of building one Wellington per day.Construction took longer to build due to the geodesic fuselage in comparison to other designs using monocoque approach, leading to criticism of the Wellington.In particular, it was difficult to cut holes in the fuselage for access or equipment fixtures; to aid manufacturing, the Leigh light was deployed through the mounting for the absent FN9 ventral turret.
