TheBoeing Model 2, also referred to as theBoeing Model C, and its derivatives wereUnited States two-placetrainingseaplanes, the first "all-Boeing" design and the company's first financial success.
TheBoeing Airplane Company, previously known as Pacific Aero Products Co., built the Model C naval trainer as its first mass-produced airplane. Early design work was started byGeorge Conrad Westervelt in late 1915, with the first wind tunnel tests being conducted at theMassachusetts Institute of Technology's 4 ft (1.2 m) wind tunnel in May 1916. Most of the design work during early-to-mid 1916 by James Foley, who had previously assisted Westervelt in designing the Boeing Model 1. Westervelt, who had been reassigned to the East Coast in December 1915, consulted heavily on the design.Wong Tsu, an MIT graduate who was hired by Boeing in May 1916, also contributed to the design, specifically lending his expertise in the analysis of wind tunnel data. A total of 56 C-type trainers were built; 55 used twin pontoons. The Model C-1F had a single main pontoon and small auxiliary floats under each wing and was powered by aCurtiss OX-5engine.
The success of the Model C led to Boeing's first military contract in April 1917 and prompted both its reincorporation as the Boeing Airplane Company and relocation fromLake Union, Washington to a former shipyard on theDuwamish River, also in Washington. TheUnited States Navy bought 51 of the Model C trainers, including the C-1F, and theUnited States Army bought two landplane versions with side-by-side seating, designated the EA.
The final Model C was built for William Boeing and was called the C-700 (the last Navy plane had been Navy serial number 699). On March 3, 1919, Boeing and Eddie Hubbard flew the C-700 on the first international mail delivery, carrying 60 letters fromVancouver,British Columbia toSeattle,Washington.
