The 4 AT built for the Standard Oil Co. had a cabin equipped with three berths which could be converted into beds at night. The walls of all the cabins were padded with kapok for noise reduction. Large observation windows (which could be opened or closed for ventilation) were located in the cabin walls. Behind the cabin were an equipped washroom, toilet and a space for baggage. The cabins were provided with an exhaust heater.
When the Curtiss-Wright and American Airways designers were working out the details of the Condor sleeper plane they evolved an arrangement of berths very much in the Pullman tradition. The berths of the Fokker XXXVI resemble those in European Wagon-Lits. The Fokker berths were segregated into compartments of four.
Private aircraft in 1939 were designed for better vision and had fewer things for passengers to fall over getting in and out. The photo caption in the original article reads, "There’s plenty of room for the family in the rear seat of the Stinson SR 10C."
Passengers on Air France's luxury schedules between New York and Paris in 1947 rode in late-model Constellations with berths for 22 people or daytimes seats for 44 travelers. All berths were 6 1/2 ft. long and as wide as three-quarter beds. Upper berths were made up before the plane's departure. The interior featured French motif in rose beige and chartreuse, scheme Air France found restful to passengers.
Mockup Shows Interior of East German BB-152 in 1958
Aviation Week Archives
Mockup of East Germany’s BB-152 jet transport in 1958 shows that the aircraft, designed by Prof. Brunolf Baade, would have Viscount-type windows that could be used as emergency exits. Interior would be decorated in shades of blue, from light to dark, with contrasting brown. Overhead racks did not combine services such as lights, call buttons.
Pictured here is the upper deck berth installed by Japan Air Lines in its long-range Boeing 747s. Berths were 6 ft. long and 2 ft. 3 in. wide, with a curtain visible at the right. It could also be used as a lounge seat.
