It takes placing your hand on a armed 767's emergency handle and that door will blow like a rocket.
I personally have been on a flight where a passenger attempted to open the door in flight. He was strong enough to begin to rotate the handle and after subdued, we could not get the handle to go back down and had to re-seat pax and remain away from the door.
So here is my take on it, you want to look outside and you don't have a window seat? Learn over a your neighbor and look out, but be sure to stay away from my door, no matter how small a risk and impossible it is to open. Those windows are mostly useless unless you are looking for fire,smoke,water, or large debris. ^
I will question someone like you who comes on here conteptiously and arrogant and yet is completely wrong!!!!!
Yes..you may know how to operate the doors...but you certainly don't understand anything about how they function. The 767 door does indeed stow up into the overhead but the door itself is still larger than the fuselage cut out and when operating the door it actually travels inward a few inches. It is this inward travel that is prevented by the pressurization. The 777 door does not open outward and then forward...think carefully....it initially travels inboard a few inches when you rotate the handle through about halfway and then starts to swing out. Again, it is this inward travel at the beginning that makes it impossible to open the door inflight.
As to the emergency operation of the 767 door I can not speak since I don't have specific knowledge of it but take the 747-400. The main deck doors are all plug-type and operate like the 777. The upper deck doors are not plug type however they have a lock-out mechanisms that engages when the plane senses that it is airborne. This is straight from the Boeing manual:
An automatic lock activates in flight to lock the upper deck door operating handles to prevent inadvertent operation. If the upperdeck door automatic lock fails to operate after take-off, the EICAS caution message DOOR U/D FLT LK is displayed and the blue Door Ground Mode Light above the affected door illuminates. In this condition it is possible to open an upper deck door when cabin differential pressure is below 3 PSI.
As for the pax rotating the handle...as was mentioned before..yes someone can rotate it but you still can not open the door. The amount was minimal..only up until the point where the door itself would actually start to move, remember, the first bit of travel by the handle is for the mechanism that disengages the GERT bar. The reason you would have to keep pax away from the door with the handle not stowed in the closed position is to avoid potential harm during descent as the cabin pressure descends as this WOULD allow for the door to open.
