New jet air transport. The Vickers Viscount is the first civil transport powered exclusively with propeller - turbines. The aircraft is designed as a medium sized civil transport carrying up to 32 passengers at high altitude in an air conditioned, pressurized cabin. An exceptionally high standard of passenger comfort has been aimed at and trials have given evidence of a full measure of achievement From the point of view of safety the Viscount is second to none. The pressure system permits cruising at the maximum of 30,000 ft with internal conditions equivalent to an outside altitude of 8,000 Stock Photo
