Not quite. Aircraft doors are "plug type" -- they are tapered so they
CAN NOT swing out.

What happens is an incredibly complex hinge lets them swing in, turn
90 deg to the opening, pass out, and swing around. The top and bottom of
the doors retract in so they can pass through.

The plug design assures that the door can not be forced out; the frame
would rip out of the body first. And if the aircraft is pressurized, you
can't pull it in either. [1]

At least some aircraft made it much easier; on the L-1011 and ?767?; the
door did not swing at all. It translated inward [parallel to frame] then
slide up tracks al-la a house window.

1] A SWAG on the order of magnitude of the forces: A 777 door has an area
of about 3300 in^2. It looks like JB's aircraft had a differential of
about 9 psi. So that's ~30,000 lbs pushing out. Pull REALLY hard it get
it open, folks...
