NASA already buys its hardware from private industry so "commercial
space launch services" can only mean a relaxation of NASA's influence
on the design specifications. But NASA's specs are already too loose
(on the shuttle and Ares 1 for instance). I predict safety will
suffer if we go over to privatized crew launch services. The right
thing to do is restrict commercial space launch to cargo only and pay
only for successful delivery. The airline industry was paid for MAIL
transport in the early years! i.e. cargo only!
