Pax Threatens To Open Door On WN MDW-SMF Flight

Mon Apr 14, 2014 6:31 pm

Hope I'm not repeating a post here. I did a quick scan and didn't see anything. See the story below from WMAQ here in Chicago about yesterday's diversion of WN722 (MDW-SMF) to OMA after a passenger threatened to open a door in flight.

You'd think I'd know, but I don't.... Would it not be impossible to open a door (or exit) midair because of either locking mechanisms and/or physics?

On a 737 it's impossible; the main doors are plug-style, and the overwing exits are electrically locked above certain speeds during takeoff roll.

The A320, on the other hand... does not use plug-style doors. Rather, they drop vertically into locked place, and I don't know whether they're electrically locked at that point or not.

All cabin doors are plug doors when they are closed and locked. On outward moving doors, such as the A320, but also on airstair doors such as seen on the Q400, there are various seats and stops that the door rests on, and cams that lock the door into place, whose operating mechanisms would snap before the cams budged given the air pressure load on the door.

I've seen this happen before, The Problem is related to Claustrophobia,
The passenger feels trapped and out of control.
Former Raider's coach John Madden has the syndrome as well. Some people need to feel in charge of their surroundings and being an an airplane where they can't see who's driving or be able to Druve themselves is maddening to tham.
This guy had better take the BUS next time he needs to travel.
Flying is hard enough without people like HIM on board. Some folks don't NEED to fly.
We've had fear of flying classes for YEARS at United. I personally know of a number of divorces because of it

This is best part of this story!! CBS morning show has omaha in Kansas on the map when referring to the story. Niiiccceee! Whoever made this map should be fired for not knowing some basic 5th grade geography! funny but sad.

You're not an airline mechanic, are you?

What you've said is like saying that all cars are minivans, once loaded with people.

Cams and rollers DO NOT a "plug style" door make.
And the A320 main cabin doors are NOT plug doors. They may have mechanisms that accomplish the same goal, sure. But a plug door is larger than the opening through which it translates, and the A320- and many newer Boeing designs- are not of that type.

It sounds like a mentally ill person who is not taking their medicine. This seems to be case on many incidents on flights like this. As someone who has a mental illness, seeing things like this happen continually remind me of the importance of taking medication and listening to the doctors. Mentally ill people can live normal lives, as long as they are not reckless with their decision making and go off of their medicine. I've done it before and it's not pleasant.

Hey, I'm trying to dumb it down for the OP so that he understands that the door cannot be opened because of mechanical stresses caused by air pressure and how the door is rigged, but you're more than welcome to overload the guy with engineering babble if you wish.

And that's a terrible comparison.

Oh, well, Kansas and Nebraska are neighbor states, so it was really only a minor inaccuracy. If only the press never provided information way less accurate than that, then we would all be a lot better informed.

You are right that they are electrically locked but they lock when the throttles are advanced and the engines accelerate. If you are sitting next to the door and know what to listen for you can hear them lock. I have had to change a few of the solenoids due to failure. You get a PSEU fault when they fail.

Funny, I used to work for a guy whos child was autistic, fortunately they were wealthy enough to afford one of the best schools in the country. Three unfortunate things were, the school was in Boston, we all lived in Portland OR, and the kid would not fly, so twice a year my boss would fly one way, and take Amtrak with the kid in a sleeper car.

Wow, sorry to hear that man. It's sad when something ends that was once beautiful. But I honestly had never heard of a couple divorcing someone because they can't fly and the other loves to fly. But this is an honest feeling, and I get it. I'm sure it was far more complicated than that, thanks for sharing.

You make perfect sense, I have a partner that suffers with mental illness, and we have been fortunate enough to find a Dr who really cares, and he found a once a month injection of a drug called invega. No more daily meds to remember or forget as was most of the time. The alter ego is a tough person for me to cope with, a reason I didn't fly for 5 years, I never knew when the other side would show. Now we regularly go to Hawaii and he sleps most of the way, even in F. Thanks for the honesty, and the promotion of mental awareness, something very dear to my heart. Peace!
