National Air Transport (NAT) National Air Transport was an early American airline founded in 1925 that operated mail and passenger services during the interwar period, linking Midwestern and transcontinental aviation networks and interacting with major aviation figures and corporations. The company engaged with the United States Post Office Department mail contracts, collaborated with aircraft manufacturers and financiers such as William Boeing, Glenn L. Martin, Curtiss-Wright Corporation, and financiers tied to JP Morgan and Walter Chrysler, and participated in the consolidation that produced larger carriers including United Airlines and influenced regulatory discussions around the Air Mail Act of 1930 and the Air Mail Scandal.
National Air Transport was founded in 1925 amid the post-World War I expansion of commercial aviation and the implementation of the Contract Air Mail system, following precedents set by companies like Airmail Service (US) and organizers from Kelly Field. Early leadership included entrepreneurs and aviators linked to William Boeing, Glenn Curtiss, Donald Douglas, and executives who later interacted with United Aircraft and Transport Corporation. NAT secured lucrative airmail contracts awarded under policies from the United States Post Office Department and operated through economic episodes such as the Roaring Twenties and the Great Depression. The carrier's corporate trajectory intersected with the Air Mail Act of 1934 restructuring and industry consolidations that involved companies like Transcontinental Air Transport, Western Air Express, and eventually United Airlines.
NAT provided overnight and daytime airmail services under contracts from the United States Post Office Department, supplementing mail routes established by predecessors tied to Army Air Service route surveys and commercial pioneers like Benjamin Franklin "B.F." Mahoney. Passenger operations included early scheduled coach and charter flights connecting urban centers such as Chicago, St. Louis, Kansas City, and Cleveland and offering connections that interfaced with railroads like the Pennsylvania Railroad and companies such as Pullman Company. The airline also performed promotional exhibitions with aviation personalities including Charles Lindbergh and Eddie Rickenbacker, and coordinated weather briefings influenced by the United States Weather Bureau for operational planning.
The NAT fleet comprised contemporary mail and passenger aircraft sourced from manufacturers including Boeing, Curtiss, Douglas Aircraft Company, and Stinson Aircraft Company. Typical types used were mail-configured transports and small passenger airliners analogous to the Boeing Model 40, Douglas M-2, and Stinson Detroiter family, reflecting designs influenced by wartime developments from World War I contractors such as Vickers and Hawker. Maintenance operations leveraged facilities and technicians associated with aviation suppliers like Pratt & Whitney for powerplants and avionics suppliers linked to Radio Corporation of America for communications equipment.
NAT's ownership and management involved investment from Midwest financiers and connections to industrial conglomerates similar to those behind United Aircraft and Transport Corporation, with board members and executives interacting with figures tied to JP Morgan, W. Irving Glover, and executives parallel to Edward Hubbard "Eddie" Rickenbacker in leadership roles. The company participated in mergers, acquisitions, and inter-company agreements with carriers such as Transcontinental Air Transport, Western Air Express, and manufacturers like Douglas Aircraft Company, producing complex corporate links scrutinized during investigations by Congressional panels and influenced by legislation including the Air Mail Act of 1930 and later reforms.
Operating from a principal base at Chicago Municipal Airport and serving Midwestern and transcontinental corridors, NAT established scheduled routes linking urban centers including Chicago, St. Louis, Kansas City, Cleveland, and onward connections to coastal gateways like New York City and Los Angeles via interline partnerships. The route network mirrored mail route maps issued by the United States Post Office Department and coordinated with regional airfields such as Midway Airport predecessors, municipal airports in Cleveland Municipal Airport and St. Louis Lambert International Airport origins, and logistical nodes tied to railroad terminals like Union Station (Chicago).
NAT's safety record reflected the broader challenges of early commercial aviation confronting navigation limitations, weather-related risks, and nascent air traffic procedures; incidents involved forced landings, mechanical failures, and pilot error similar to contemporaneous events affecting Transcontinental Air Transport and Western Air Express. Accidents prompted investigations by authorities linked to the United States Department of Commerce aeronautics branch and influenced the development of regulations and navigational aids promoted by institutions such as the Civil Aeronautics Authority precursor organizations. High-profile incidents contributed to public and legislative scrutiny during the period of the Air Mail Scandal.
National Air Transport's integration of mail and passenger services, participation in airmail contracting, and involvement in corporate consolidations played a formative role in shaping modern airline networks and corporate structures that evolved into major carriers like United Airlines and influenced regulatory frameworks culminating in agencies such as the Civil Aeronautics Board. NAT's operational practices informed standards adopted by aircraft manufacturers—including Douglas Aircraft Company and Boeing—and its interactions with federal policy influenced the development of air navigation, mail logistics, and commercial route planning that underpinned later expansions involving carriers like American Airlines, Delta Air Lines, and Pan American World Airways.
