context_page_description: Enea Bossi Sr. was an Italian-American aerospace engineer and aviation pioneer. He is best known for designing the Budd BB-1 Pioneer, the first stainless steel aircraft; and also the Pedaliante airplane, disputably credited with the first fully human-powered flight.
context_section_description: The Edward G. Budd Manufacturing Corporation, of Philadelphia, Pennsylvania, was a major manufacturer of railroad cars, which resulted in significant experience in working with stainless steel. In 1930, the company made its first foray into the aviation industry by signing contracts to manufacture aircraft wheels & stainless steel wing ribs. A close friend of Edward Budd, Enea Bossi joined the company as the head of stainless steel research to supervise the design and construction of the 4-seat Budd BB-1 Pioneer – the first aircraft with a structure built out of stainless steel . Occurring in 1931, this was the first aircraft for the Budd Company. Built under Restricted License NR749, its design utilized concepts developed for the Savoia-Marchetti S-31 and was powered by a single 210 horsepower (160 kW) Kinner C-5 motor.
  The stainless steel construction process for the BB-1 was patented in 1942.  At the time, stainless steel was not considered practical; and only one BB-1 was built. In 1934, this plane was stripped of its fabric covering and mounted outside the Franklin Institute in Philadelphia, where it remains to this day as the longest continuous display of any airplane.  The plane has been memorialized in the children's book Spirited Philadelphia Adventure by Deirdre Cimino.  In 1931, Bossi sold the controlling interest of the AAC to Dayton Airplane Engine Company.  The success which came from the technical innovations of the BB-1 prompted the Budd Company to employ Bossi as its European representative.
