Whitney, and Sikorsky. Carrier is the world’s
largest maker of heating and air-conditioning
units and Otis is the leading elevator maker.
Hamilton Sundstrand makes engine controls,
environmental systems, propellers and other
flight systems. Pratt & Whitney makes aircraft

and Pratt & Whitney Aircraft. Others joined the
holding company, as did some airlines. In 1934
it was split into three companies, United
Airlines, Boeing and a new United Aircraft
Corp., (Pratt & Whitney, Sikorsky, Vought and
Hamilton Standard Propeller). United Aircraft
became United Technologies in 1975. In 2004,
UTC acquired the Schweizer Aircraft Corp.,
which operates as a wholly-owned subsidiary
under the Sikorsky Aircraft division. In 2007,
UTC opened the Hawk Works, a rapid
