@arstechnica I kinda feel like Starliner is Sheldon knocking on Penny's door, and she opened it before he could get out the third knock-knock-knock-Penny. Apart from the /possibility/ (what are the odds of needing a second "crewed flight test"?) of having a "second source," I really don't see any point in Starliner. Boeing blew it. Starliner is years behind (in operational experience and improvements based on it), far more expensive to fly, and seems like a much more limited spacecraft.
