Interesting that way back in its history United and Boeing were one company until the government ordered the split of the manufacturing side from the transportation service side.
United Aircraft & Transport Company was formed by Bill Boeing in 1929-1930, as he put together the manufacuring companies Boeing Airplane Co, Pratt & Whitney, Chance Vought; Hamilton Standard Proppeller Co, Sikorski, Stearman, Northrop AircraftVarney, to the transportation compnaies--his own Boeing Air Tranport, and then Pacific Air Transport PAT , to which they then added the acquired Varney and National Air Transport NAT.
In 1934 the government ordered the split up of what was by far the dominant aviation enterprise in the US, with the Boeing Aircraft and Stearman being split off and becoming free standing. while the other manufacturing companies spinning off to creat United Aircraft, and the transportation subsidiaries becoming United Air Lines.
What the old timers must be thinking in their graves! They now have a relative start up, Airbus, and a ''foreign'' company at that, in a leadership role in what are effectively United Airlines new group of owners. The existing shareholders are most certainly wiped out, perhaps not formally yet by means of a judges reorganization decree, but de facto.
