Teasing. Good though for reassurance now that I am thinking about it.

But then there are those Twilight Zone episodes. (winking)

Those flight attendants are really on the ball! They are looking out for anything nefarious.

...as soon as the scanner thingie goes beep, I look the gate agent in the eye and say, "I am able, prepared and eager to perform all emergency exit row functions!"

otherwise the lower outside pressure compared to cabin pressure seals the door.

But it's nice to know that it's even verified! LOL

Until this happened, I didn't realize anyone could open doors on a commercial aircraft unless the doors were unarmed by the flight crew.

The fact that doors can be opened during take-offs and landings are a concern. Ask the folks on the Asiana flight if you have doubts. And note that Asiana has stopped selling seats next to emergency exits.

There have been instances when doors have departed the aircraft from not being properly secured. Generally this happens shortly after takeoff and to my knowledge there’s never been any casualties from the event other than the massive cost of repairing the aircraft.
