- The prediction was for a somewhat higher startup cost (including
- retraining, buying expensive Ada compilers (as though there were any
- other kind), and so on), and I suspect what happened is what you
- wrote: the higher startup cost was iterated over the program lifetime.
-
- Of course, I'm sure there are/were other political, and possibly
- financial, reasons for not using Ada on this particular project. None
- of the ones I've heard make any more sense than the $45 million delta.
