I've had a go at building the transport shown on the front cover, thanks to Chris who supplied the drawings to me last year.
in 1964, the Air Staff published AST.364, which called for an aircraft capable of transporting 100 klbs (45 tons) over 5000 nm (9200 km) at a speed of 500 kts (900 km/h), for use as a strategic transport on Far East routes. BAC submitted this design using the Vickers VC-10 heritage, with the wings and tailplanes being scaled up by ~25% from the VC-10 items. A new fuselage was designed, with a side-hinged swing-nose. Engines were RB.177 Medway variants.
