Two problems- historically, they've killed almost 1% of the humans
they've tried to launch. That ain't "safely" in my book. Second, the
big market, the real enabler for routine cheap access to space, is space
tourism. Leaving manned space flight in NASA's hands is like building a
luxury island hotel, then using an F-18 to deliver guests via ejection
