- This more clearly illustrates my point Allen. You have to include
- the use of clean rooms and pif's etc. They are not always available.
- (I am not talking building costs, those are one shot and are amortized over
- the years, becomimg I would assume a small part of the cost). BUt
- for more flights you have to increase the number of "standing armies" of
- technicians, the number of facilities (so that at least one is always

- Up to a point. This is like saying that the more cars that use a toll-bridge

- across. Then your profit drops in half.
