One more Shuttle disaster and Congress will put us out of
the manned space flight business permanently. But NASA will
never give up the Shuttle cash cow it has been riding for
almost half a century for a safer, better industry designed
system.

Study was done in the past concerning space flight cost.
The conclusion
was
that space flight cost will never come down close to jet
flight cost.
Typical airliner flight consists of flying to point A to
B, refuel, pilot
gets out and kick the tire, and fly back to point A.
Typical space flight
is totally different. Space craft leave for orbit, come
back, technicians
must go over and certify all systems for flight
worthiness before the next
flight. That includes checking every inch of external
surface. The space
system consequently has terrible turnover, not to
mention capacity of
delivery is a fraction of system weight.

Only if it is something designed by NASA. It is possible
to build craft that
opperate in very demanding environments that don't require
a standing army.
The SR-71 and DC-X are the classic examples.

You'll never make something that is as cheap to operate as
a 737 but there
is a three orders of magnitude difference between the cost
of a flight and
the cost of a launch. There should be some room for
improvement.
