The Saro A.21 Windover was of similar configuration to the Cutty Sark but was larger and had three Gipsy II engines and could accommodate a crew of two and six passengers.

The BAC One-eleven was designed as a turbojet successor to the VICkers Viscount series of airliners and, although it was not as successful in sales as that aircraft, some 220 odd were delivered in a variety of variants.
