Re: Thrusters
I work in aerospace. Boeing is running the old injector razor scheme.
The injector razor was a supposed improvement over the the double edge safety razor. The manufacturer reportedly sold the handles at a loss then charged more for the razor blades. Computer printers run a similar scheme. Printer manufacturers typically make very little profit on the printer but the printer locks user into buying the manufacturer's printer cartridges at exorbitant prices.
Boeing may lose money on the development of the Starliner but once it has been accepted, the profits from service and support would be enormous. Well, they would be except now Boeing has a competitor who can deliver the same services for less.
