It's built to haul an all up M1 Abrams in and out of a 5,000 foot field. You don't need a floor and a ramp like that to carry broccoli or DVD players.
Anyway, the time to start thinking about what to do with the C17 outside of military applications was fifteen years ago.
The building is probably, and the tools inside it are for sure owned by Uncle Sam, including what was the largest Drivematic machine in the world at the time. Boeing had no proprietary interest in the program as none of their money was on the line. Boeing's interest in the program was only in milking out every nickel from the order book, and not developing or promoting what they bought down in Long Beach.
Building heavy aircraft is like a lot of other technology and resource dense enterprises-it is far easier to start with a going operation than to build it from the ground up.
It is common in such industries to buy up and idle potentially competitive production facilities, because it raises the bar for any potential entrants in the market. Douglas was on the market, had been offered to Taiwan, and others may have been interested. We see such things in the midwest, as the larger meatpackers buy up and idle productive capacity as a bar to entrance of local folks when they get too big for their britches. One of my clients did this in a specailized metalworking trade.
When the order book runs out and the place is turned into golf condos, the expertise and infrastructure that could support heavy aircraft manufacturing in the area will be long gone.
It's quite clear that the reason they bought Long Beach was to make damned sure that heavy jets were not built anywhere in this country but north of the Columbia River.
