Overair has doubled the size of its California headquarters as it steps up efforts to bring its Butterfly eVTOL aircraft to market in 2026. The new facilities in Santa Ana consist of a pair of buildings, respectively 94,000 sq ft and 109,000 sq ft in area, encompassing offices, shop lab space, and clean rooms for aircraft design, development, and manufacturing, as well as separate areas for systems integration work and testing.

According to the company, the expansion of its premises near John Wayne/Orange County Airport has been timed to coincide with its transition from the design phase of the Butterfly program to certification and scaled production. In a November 4 announcement, it said that it intends to hire around 1,000 employees over the next three to five years, including aerostructures and propulsion systems engineers.
