The purpose of testing is to weed out problems, and then fix them. This is a concept that is foreign to members of the "press", who salivate at every opportunity to criticize the military in general, and military R&D in particular.
This is technically a poor approach to a problem that doesn’t need solving.
The cowards in the Senate and at State, just don’t want the obvious and workable solution.
True, R&D is an evolving process.
The Boeing solution is stabilized and prototypes have flown as far back as the late 60’s. LM is testing an unproven design that carries less payload than the Boeing design.
Why go with a more costly, untested and unreliable system?
