- First of all, this is being done to test the concept. Most (not all) of
- the parts exist but they are still being used in a new way. The key is the
- parts which don't exist yet and to veryfy the overall concept. Since DC-Y
- is an experimental craft then we will have a nice testbed to try new
- ideas. For example, after DC-Y flies we can replace the engines with
- aerospike engines and see if performance improves.
-
- Second of all it the issue of risk. We are currently in a catch-22: nobody
- launches much because costs are too high and costs are too high because
- nobody luanches much. SSTO offers the promise of greatly reducing costs
- and thereby opening the markets.
