Coincidentally, Burnett Bond was a close friend of Bertha Potter (wife of William E. Boeing), being both her godmother, and living with her family while she attended finishing school.Due to its location on a large body of water, the Navy Department worked to establish a flying boat aircraft factory on the land for production of the Boeing XPBB Sea Ranger.The Renton plant would also be used as a shipbuilding facility from 1974 to 1985, building the Pegasus-class hydrofoil for the Navy, and commercial Boeing 929 jetfoils alongside the aircraft production lines.[4] The plant was briefly closed at the end of World War II, but by 1949 it was re-opened to build the Boeing C-97 Stratofreighter for the United States Air Force.Nicknamed the "Dash 80," the prototype rolled out of the Renton factory in May 1954 and would become the basis for two different production aircraft: the military KC-135 Stratotanker and the 707, the first successful commercial jetliner.The Renton factory also produces airframes for the P-8 Poseidon, a maritime patrol "submarine hunter" aircraft for the United States Navy.
