"There’s no way for a person to open a door while a plane is pressurized in flight"

Let's do some quick math, if that doesn't upset common-core too much:

Air pressure at 35,000 feet: 3.7 pounds per square inch.
Air pressure at 7,000 ft cabin pressure: 10.2 pounds per square inch.
Pressure differential: 6.5 pounds per square inch
Approximate cabin door size: 72x30 inches, = 2,160 square inches.
Pressure required to open door: 14,040 pounds.

He's going to need a LOT of help to get that door open.

So, yer sayin'...

It would take 7000 200lb men pulling on that door to get it open.

Logically, I know that. No unaided human would have the strength to open that door while in flight. Still, it’s deeply disturbing to see someone trying to make that happen.
Air travel already seems kind of magical to begin with.
Yes, it’s true, I’m not an engineer, mathmatician or mechanic. How did you guess?

You are also assuming the person is trying to open the door the correct way. :)

Hey if they are trying to open the door at all, you have to consider they may be pulling when they should be pushing.

Is there not a mechanical assist when the level is pulled, thereby making it possible for one nut to open it? Also, how was it possible for D.B. Cooper to do it?

Probably even more importantly, the door are all “plug doors, which have to be brought inward, turned 90 degrees then pushed outward through the hole into which they are fitted. The lock pins just keep the door from being able to be moved inward.

WOW! That's like Gov Chris Christy in his beach wear leaning against the door, while you're trying to open it.

Good info.. I wasn’t aware. However, you think a flight attendant would be.
