Actually it was a three way split. Pratt & Whitney (hence the holding company still being "United Technologies"), United Airlines (ex-Boeing Air Transport) and Boeing Aircraft. Hamilton Standard (propellers), Sikorsky, and Chance Vought were also in the combine. It was broken up under US anti-trust laws in the early 1930s.
