When William Boeing founded the company that bears his name, he was planning to build seaplanes.

Explanation:

William Edward Boeing was a pioneer of aviation, founder of the Boeing company.

In 1910, Boeing attended an aerial demonstration in California and since then he discovered his interest in the aeronautical world. Five years later, he managed to learn to fly in Los Angeles and bought his first plane, a Martin's seaplane. These first amateur flights were little by little becoming professionals. Boeing and his friend G. Conrad Westervelt designed parts of the plane that they found likely to be improved over the initial design.

Years later, in 1916, Boeing founded the company Pacific Aero Products, just a year before the United States entered the First World War (1917). The building that was the first aircraft factory was located next to the Duwamish River and was a barn made of wood called the "red barn". Boeing changed the name of the company to the Boeing Airplane Company and began obtaining orders from the US military.
