The BB-1 seaplane, another new commercial aircraft, makes its first flight. It is bought by a Canadian and becomes the company's second international sale. The Boeing BB-L6 makes its first flight. Built for Herb Munter's aerial tours, it is the first airplane to fly over Mount Rainier. A week later, the contract is reduced to 10 airplanes.
Rumors say some of the buyers are Prohibition-era liquor smugglers.
This is the first known nonwage benefit at Boeing. Eddie Hubbard is awarded the Collier Trophy for day and night flying service delivering mail between Seattle and Vancouver, British Columbia, in his B-1 . Pilot Frank Tyndall takes the Model 15, prototype of the first company-designed fighter, on its first successful test flight from Camp Lewis, Washington. It is the first in its series, developed for the Navy from the Model 15. The Army and Navy eventually buy more than 157 derivatives of the Model 15.
