Boeing 80

From Wikipedia, the free encyclopedia

Model 80
Type	Airliner
Manufacturer	Boeing
Maiden flight	27 July 1928

The Boeing 80 was an early United States airliner. It was the first purpose-built airliner for the Washington aircraft company Boeing. A biplane like its predecessor, the Model 40A, it was significantly larger, with three radial engines, an enclosed flight deck for 2 pilots, and a cabin for 12 passengers. A larger model, the 80A, increased passenger capacity to 18, making its first flight on September 12, 1929. Ten Model 80A aircraft flew for the Boeing airlines.

Despite complaints by pilots accustomed to flying in an open cockpit, the size of the Model 80 required a separate, enclosed flight deck. The Model 80 carried passengers in a spacious cabin appointed with leather upholstery, reading lamps, forced-air ventilation, and hot and cold running water.

The 80A also introduced aviation's first female flight attendants, when registered nurse Ellen Church convinced managers at Boeing women registered as nurses would be a useful part of an aircraft's crew.
