You couldn't open a door by hand on an airliner at altitude if you tried -- with 3 of your friends.

wait a minute... isn't that backwards? The higher pressure wants to rush to the lower pressure, to equalize. So the door would want to
come open.
Think about diving bells. Positive vs negative pressure.

Precisely! So they make the door opening somewhat smaller than the door itself. You can't just swing the door open. There's a
mechanism that first pushes the door inside the airplane, rotates it and vertically slides it out through a small opening on the airframe that
is of the same highth as the door. PMDG 747 has it nicely animated.
