W-1A, NASA history collection. Public domain image of NASA aircraft.

Fred Weick's homebuilt W-1A of 1934, one of the first aircraft to employ tricycle landing gear. Weick and group of nine other Langley engineers built this small experimental airplane in their spare time to study the special needs of the private flyer. The plane was eventually purchased by the Department of Commerce. After leaving the NACA (for a second and final time) in 1936, Weick incorporated many elements of the W-1 into his design of the famous Ercoupe, a small simple to fly airplane built first by the Engineering Research and Development Corporation (ERCO) of suburban Washington D.C.
