Flight Overshoots Airport by 150 Miles

Northwest Plane Returned Safely to Minneapolis Airport after Realizing Error; Pilot Fatigue Eyed as Factor

(CBS/AP)  Last updated a 10:38 p.m. EDT

Two Northwest Airlines pilots failed to make radio contact with ground controllers for more than an hour and overflew their Minneapolis destination by 150 miles before discovering the mistake and turning around.

The plane landed safely Wednesday evening, apparently without passengers realizing that anything had been amiss. No one was hurt.

The Federal Aviation Administration said the crew told authorities they became distracted during a heated discussion over airline policy and lost track of their location, but federal officials are investigating whether pilot fatigue might also have played a role.

The National Transportation Safety Board does not yet know if the crew fell asleep, spokesman Keith Holloway said, calling that idea "speculative."

The pilots didn't become aware of their situation until a flight attendant contacted them through an intercom from the cabin to the cockpit, said a source familiar with the investigation who wasn't authorized to speak publicly and asked not to be named.

Flight 188, an Airbus A320, was flying from San Diego to Minneapolis with 144 passengers and five crew. The pilots dropped out of radio contact with controllers just before 7 p.m. CDT, when they were at 37,000 feet. The jet flew over the airport just before 8 p.m. and overshot it before communication was re-established at 8:14 p.m, the NTSB said.

CBS News correspondent Nancy Cordes reports that about 10 air traffic controllers from two different centers - Denver and Minneapolis - tried to reach the pilots during the hour and 20 minutes they were incommunicado. After the first half hour, controllers contacted Northwest to alert the airline to the problem.

The FAA notified the military, which put Air National Guard fighter jets on alert at two locations. As many as four planes could have been scrambled, but none took to the air.

"After FAA re-established communications, we pulled off," said Michael Kucharek, a North American Aerospace Defense Command spokesman.

Andrea Allmon, who had been traveling from San Diego on business, said no one on the plane knew anything was wrong until the end of the flight.

"Everybody got up to get their luggage and the plane was swarmed by police as we were getting our bags down from the overhead bins," she said.

She said they were kept on the plane briefly while police talked to the crew, then allowed off. She said she was "horrified" to learn what had happened.

"When I do my job I do my job," she said. "These guys are supposed to be paying attention to the flight. The safety of the passengers should be first and foremost. (It's) unbelievable to me that they weren't paying attention. Just not paying attention."

As of Thursday afternoon, NTSB investigators had not yet examined the cockpit voice recorder and flight data recorder, which were being sent to Washington for analysis. Holloway said the agency was also seeking to interview the pilots, but had not scheduled a meeting.

A320s are equipped with a phone-like device that airline dispatchers can use to contact the crew, said Shirley Phillips, a former simulator instructor for US Airways who has flown the A320.

"It's fairly loud," she said. "There's lots of whistles and bells and things in the Airbus that all signify different things, but it has a pretty distinctive sound to it. I wouldn't say that you would mistake it for anything else."

In any case, she said the cockpit voice recorder should prove whether the pilots were arguing, as they claim.

"It literally records when they sneeze. It's going to record all the noise that goes on there."

One of the two pilots should have been paying attention to the radio, said Ronald Carr, a former Air Force and American Airlines pilot who teaches flight physiology at Embry-Riddle Aeronautical University. But he added that "sometimes you can have such heated discussions and get so distracted that you lose situational awareness, and when you're traveling seven miles a minute, that can happen pretty quick."

The two pilots have been suspended from flying while Delta Air Lines Inc. conducts an internal investigation, said Anthony Black, a spokesman for the Atlanta-based airline, which acquired Northwest last year. He refused to name them or give further details on their background or what happened in the air.

Air traffic controllers in Denver had been in contact with the pilots as they flew over the Rockies, FAA spokeswoman Laura Brown said. But as the plane got closer to Minneapolis, she said, "the Denver center tried to contact the flight but couldn't get anyone."Denver controllers notified their counterparts in Minneapolis, who also tried to reach the crew without success, Brown said. Controllers and the pilots finally resumed communication when the plane was over Eau Claire, Wis.

"Radar controllers were the whole time trying to make audio contact with that plane," said Tony Molinaro, an FAA spokesman in Chicago. He said he was not aware of controllers diverting any other flights, which was unnecessary because the Northwest jet was flying high enough to safely avoid planes approaching Minneapolis-St. Paul International Airport.

It was not clear who initiated communications when contact finally was made, Brown said.

After the plane landed, two airport police officers boarded the plane at the gate, which authorities said is standard procedure after a crew loses communication with air traffic controllers.

Kelly Regus, a spokeswoman for the Delta branch of the Air Line Pilots Association, declined to comment.

The Federal Aviation Administration is updating decades-old rules governing how long commercial pilots can fly and remain on duty. The NTSB also cautioned government agencies this week about the risks of sleep apnea contributing to transportation accidents.

In January 2008, two go! airlines pilots fell asleep for at least 18 minutes during a midmorning flight from Honolulu to Hilo, Hawaii. The plane passed its destination before controllers raised the pilots, who landed safely. The captain was later diagnosed with sleep apnea.

While fatigue is a very real possibility, please don't discount another likelihood---sex. There are gay pilots out there, so it shouldn't come as a surprise a little dallying in the cockpit (no pun intended) happens. The secretive way the pilots are acting says they're hiding something much more offensive than falling asleep or a heated argument (and now they deny the argument.) Of course falling asleep behind the wheel, so-to-speak, is the ultimate horror to passengers---but sex between two pilots in the privacy of the cockpit is the ultimate embarrassment. Before you discount me as a ditzy flight attendant, remember I've seen everything happen on a plane, so it surprises me this hasn't even come up yet.

"Oh, you said Dallas...I thought you said DULLES"

[huegorgan]

Dropped out of communication? Re-established communication? Seems to me the ATCs knew where the plane was at all times and the loss of communication occurred because of pilot error. REVOKE THE PILOTS' LICENSES and fine Northwest Airlines for hiring irresponsible employees.

[nocatnowaco]

the passengers of this flight were lucky per good weather and the plane is still carrying extra fuel in the wings. in a really, really, and really future green flight coming soon, they will ask passengers to pee and poop and skip meals before boarding and the plane will only carry enough point to point fuel.

[dakotaclark]

One would think they were required to file a flight plan with ATC/FAA.

The ATC/FAA controllers who "lost communication" with the subject aircraft, and who saw that the aircraft overshot the destination, should have been able to activate a pilot alert, something on the equivalence of a 95 decibel Klaxon Horn in the cockpit.

That would have awakened the Pilot and First Officer.

However, there is no such warning system available for use by ATC/FAA/airlines; and, maybe this is the case that should be used to justify implementing that type of warning system. Eh?

[heidiMN]

miss u not.....your sarcasm is unnecessary. The comment regarding the fighter jets is completely legitimate. Ever hear of 9-11?? The flight crew would, should, and DO check their watches. It's their job to remain aware and informed of any detail that might affect the ETA. You make the comment about how fast it takes to fly 150miles, being as the pilots were asleep they really don't care how fast it would take to get to the potential crash site now do they?

[rwsmith29456]

Unless they have RE-E-E-E-E-E-EALLY good excuse I'd expect that the pilots will be flight attendants next time they go back up.

[formrusmcsgt]

Will the frequent fliers get credit for the 300 additional miles?

[bobnjersey]

["The effect of early start times on sleep is well documented," the NTSB said. ]

so then why are the pilots initiating their day at early times three days in a row?

[Bob Fitz]

I wouldn't blame the flight attendants. Only 14 mins. lapsed and it's not their call to check their watches with detailed accuracy. They could well have thought that the flight deck was told to circle MSP due to traffic, weather etc. As for the capt. and first officer - hard to believe the story that they were in a heated discussion and not asleep. Of course the CVR will reveal that one. Even if they did fall asleep firing them seems excessive to me. That's the economic death penalty. Two months out of service instead would get their attention. Then put them through retraining and never let the two fly the same flight again.

[credibility2]

They both should be fired. Why didn't the controllers try to get the fighter jets to check them out. For all they knew, they could have been hijacked. The flight attendants apparently weren't paying attention either, since this was probably a routine flight and they should have been able to check their watches. The pilot always announces the time before takeoff and the length of the flight and the anticipated arrival time. Was everyone on board brain dead, or what?

[stuart-johns2]

I agree. Normally I would'nt but in this job? I mean what do you do...pull over to the nearest cloud, get out and make a call to AAA?

Too many lives at stake for this nonsense. Totally inexcusable and unacceptable.

[missme4]

@credibility2
Obviously your intelligemce has no crerdibility. How would fighter planes wake them? Honk their horns? Put a couple of rounds into the cockpit? Why should pilots be fired? When you are exhausted you sleep. Should they have snorted some cocaine before the flight to stay awake? Why would the flight crew have checked their watches? You have any idea how fast a jet can fly 150 miles? Flights are always late. Since they were probably americans on board, chances are good that everyone on board was braindead. The government must do all their thinking. The government must tell them when to be afraid, that is why nobody was alarmed. It is america. Nobody is supposed to think for themselves in america. That is why you have politicians and lawyers, so you don't have to think. It is good to see you fit in.
