Technical Description
The Tudor was a low-wing cantilever monoplane with four engines, a single fin and rudder and a retractable tailwheel undercarriage (in its original configurations).
The wing was of NACA 23018 section at the root, and was a five-piece, all-metal, twin-spar structure. The untapered centre section carried the inboard engines and main undercarriage, while the inner and outer sections were tapered on their leading and trailing edges, with the inner sections carrying the outboard engines. The ailerons were fitted with trim and balance tabs, and there were hydraulically-operated split flaps in three sections on each side of the trailing edges of the centre section and inner wings. A 3,300 imp gal (15,000 l; 4,000 US gal) fuel capacity was given by eight bag tanks, one on either side of the fuselage in the centre section and three in both inner wings.
The all-metal tail unit had a dorsal fin integrated with the fuselage, and a 43 ft (13 m) twin-spar tailplane with inset divided elevators. The control surfaces were mass-balanced, and each had controllable trim and servo tabs.
The circular cross-section fuselage was an all-metal semi-monocoque structure, of 10 ft (3.0 m) diameter, fitted with kapok-filled inner and outer skins above floor level. The hydraulically-operated main-wheel units were similar to those of the Lancaster, had single Dunlop wheels and retracted rearward into the inboard engine nacelles. The twin tailwheels retracted rearward into the fuselage and were enclosed by twin longitudinal doors.

“Once a child has demonstrated his capacity for independent functioning in any area, his lapses into dependent behavior, even though temporary, make the mother feel that she is being taken advantage of....What only yesterday was a description of the child’s stage in life has become an indictment, a judgment.”
