At least it takes the edge off the kangaroo court they've already been subjected to. No it shouldn't have happened, but the media painted it mercilessly negative.
It looks like there may finally be a more plausible explanation regarding how the Northwest "overshot" pilots flew more than 100 miles past their destination of Minneapolis on a flight from San Diego in October. When that news broke, it topped national headlines for nearly a week. TV station CBS 4 of Denver says it "has learned the pilots of Northwest Airlines Flight 188 were first in touch with Canadian air traffic controllers after losing radio contact for more than an hour raising the possibility their cockpit radio had been tuned into the wrong frequency."
CBS News picks up the story from its Denver affiliate, saying "the final communication before the (pilots’) radio blackout was from the Denver air traffic control center. But when contact was finally resumed, the pilots turned up on a different frequency, speaking with controllers in Winnipeg, Canada." The Winnipeg contact came after U.S. controllers had been trying to reach the flight for nearly 80 minutes.
