- I can too, but they all cost money and require developments beyond
- a simple SSTO to LEO. Without costing them out, including them in
- SSTO mission cost profiles against more conventional systems is bogus.
- Without costing them out, there is no assurance at all that they will
- lower systems costs. It's like saying that a Pinto is cheaper to develop,
- buy, and operate than a unit train so we should deliver coal to power
- plants in the trunks of millions of Pintos.
