Que les parece esta historia, de las razones del error:
...On their flight from San Diego to Minneapolis, after passing Denver, the f/a called the cockpit to let them know Tim's crew meal was ready. Tim was the "flying pilot" on this leg, so he told his F/O that when the f/a brings the meal up, he will step back to use the restroom. When Tim returned, the F/A left the cockpit and he began to eat his crew meal. When a pilot leaves to use the restroom, it is customary for the other pilot to brief him on his return on "any changes", such as altitude, heading, course changes or atc center frequency changes, etc. In this instance, nothing was said....even though the f/o had received a frequency change. The problem that occurred was that the f/o never got a response on the new frequency....it was not the correct frequency....it was a Winnipeg Canada Center Freq.
Now, Denver Center is trying to get a hold of them because they never checked in, because the f/o had dialed in the wrong freq......that is who called them so many times....but, then there was a shift change at Denver Center and no one briefed the new controller that there was a NORDO A/C (non communications) in their airspace....so, in actuality, atc basically "lost" this a/c.....see Wall Street Journal article below.
Tim told me he heard atc chatter on the speaker and so never thought they were out of radio range.....but, of course, they were hearing pilots talk on Winnipeg Center. For non-pilots.....when we don’t hear anything for a long while...we ask atc if they are still there....sometimes they are and sometimes you are out of their area and need to find a new frequency. With this chatter going on, there was no concern that they were not being controlled.
Then Tim told the f/o that the new bidding system was horrible and that his November schedule was not what he hoped for. He mentioned that his son was going into the Army in Dec. and he wanted certain days off so he could see him off.....the f/o said he could help him, he knew more about the new bidding system. Tim got his lap top out and put it on his left leg and showed the f/o how he bid. He told me he had his lap top out for maybe 2 minutes. Then the f/o said that he would show him how to do it on his laptop. He had his laptop out maximum of 5 minutes.
Let's also add the 100 kt tail wind that they had to the discussion, not helping matters.
The f/a's called the cockpit on the interphone(no they did not kick the door, no, no one was sleeping, no, no one was fighting) and asked when they will get there. They looked at their nav screens and were directly over MSP. Because they had their screens set on the max, 320 kt setting, when the f/o called on the frequency, which of course was Winnipeg Center, he saw Eau Claire and Duluth on his screen. They asked where they were and the f/o told them over Eau Claire, which was not even close, but MSP had disappeared from the screen even though they were right over the city.
They were, as you all know, vectored all over the sky to determine if they had control of the a/c and Tim kept telling the f/o to tell them they have control they want to land at MSP, etc. They landed with 11,000 pounds of fuel (no they did not come in on fumes, but had 2 hours in an A320) and not but 15 minutes past schedule, even though they left San Diego 35 minutes late due to an atc flow restriction.
In the jet-way awaiting them were FBI and every other authority you can imagine.
