The FAA's Dvorak said the faulty Palmdale software had
been tested for about 3,000 hours on other computers. But, Dvorak said,
it "is impossible to test for every possible event."
-- [Gregg Dvorak, director of operational support for the FAA
unit that created the software installed at the Palmdale Air Route
Traffic Control Center on October 19, 2000. The Palmdale computer
system was shutdown for about four hours because of a "bad instruction"
in the computer code. More than 2,000 flights at L.A. International
airport were grounded or delayed by the shut down.]
