What I don't understand is why we are funding private companies for them to make vehicles, instead of letting NASA design the vehicles they will be using on their own. They've been doing it great for 50 years, why should we let untested companies start doing it for us? I do believe there is a place for those companies to assist NASA especially in cargo but NASA should be designing the crew vehicle. What was the rationale behind this? Has anyone even brought this up yet?
