1.   Every engineer knew that dollars-and-cents issues figured in his work, right along with boiler pressures and stress factors.

2.   And all this is happening even though engineers know full well that the most thoroughly tested computer software is susceptible to bugs, glitches and viruses.

3.   And just as engineers knew nothing about engineering before they went to school, they probably know nothing about managing unless they get some training.

4.   Auto engineers have always known that the most efficient transmission would have infinite gear ratios.

5.   Automotive engineers have long known that cars do their most serious polluting right after they are started, before their catalytic converters warm up.

6.   But the race engineer must know the truth, or it could be dangerous.

7.   NASA engineers know that during this time, the station will have to survive numerous collisions with fragments such as the one that hit Columbia last year.

8.   Only then, the panel concluded, will engineers know much sand an eroded beach needs, and how it should be applied.

9.   Only the financial engineers know for sure.

10.   The better part of a decade will pass before the McDonnell Douglas engineers know whether they can solve the problems inherent in building a round-trip rocket.
