Recently read someplace that with the 747, evac procedures state that, if a door cannot be opened due to a pressure problem, the F/A must break the window with a fire extinguisher to release pressure on the door seal. is this the case? Also, on the 747 door, center area just above the slide pack, is what looks like a small panel, not that easy to see, but gives access to something-access to what?

Break a window? I don't know if that's such a good idea. Do you know what airlines train thier F/A's for this procedure?
If there's enough pressure in the cabin and someone manages to break a window, well lets just say I wouldn't want to be near the window.

Doors like the 747's and DC-10's have a hydraulic blow out function if the door cannot be opened. It is kind of like the hydraulic blow on a small airplane if the gear cannot be lowered. I have never heard of someone being supposed to break a window in a pressurized airplane.

They are called "Plug type doors" will not open with pressure inside the cabin. Also rather impossible to even break a window with the cockpit crash axe. I have seen firefighters on demo use a axe and it was 4 feet long and it just bounced off..
