“If NASA defers to its fallback plan, flying on Dragon, it may spell the end of the Starliner program. During the development and testing of Starliner, the company has already lost $1.6 billion. Reflying a crew test flight mission, which likely would be necessary should Starliner return autonomously, would cost much more. Boeing might opt to cancel Starliner and leave NASA with just a single provider of crew transportation. That would be painful for both NASA and Boeing.”
