- Opportunity costs have little to do with the costs of DC in the
- scenario given, Allen. Opportunity cost is an economics term used to
- describe the things given up because a choice is made. The large
- opportunity cost being described is NOT being able to do certain
- things for a number of years if we scrap the Shuttle before DC is
- ready to replace it.
-
- As an example, one of the 'opportunity costs' of scrapping our prior
- capability before the Shuttle was ready was the loss of Skylab
- (because we had made a choice that left us with no ability to reboost
- it).
