- I was referring to your statment implying that Dr. Jefferys was
- contributing to the "technological myth of the century." Correcting
- Dr. Jefferys on matters of the HST is like correcting Dennis Ritchie
- on matters of C.

- While certianly a very expensive end to end test would have caught the
- trouble, assuming that such a test is even possible (which I'm not
- convinced of given the difficulty), the set of tests that you develop
- to test a mirror BEFORE you know it has a certian problem is not
- necessarily the same as the set of tests that you develop AFTER you
- know it has a problem. PE developed a system of testing that they
- THOUGHT would be good enough. Unfortunately it was not. At least we
- can be pretty sure that this blunder won't be repeated.
