Women try to open door mid-flight

What stops the door being opened at 33000 feet?

The twenty tons of air pressure holding it shut from within the cabin.

You must first pull them inwards, then outwards.

No, it is a distillation of how I usually see these things play out in the
news.

Most (not all) aircraft doors are the 'plug' type that open inward.
At altitude the pressure in the aircraft will oppose any pull on it
with a force equal to the pressure differential. Even a modest
5 psi difference would make this impossible. If the door is 70" high by
20" wide
the force holding it closed would be around 3.5 tons !

All the aircraft doors I've seen seem to open outwards. Although it's
possible the mechanism requires it to move inwards slightly first. I've
never really paid much attention.. until now.

Why don't you do a web search on aircraft doors before you make a further
fool of yourself?

How can you see things play out in the news when you haven't got a TV and
can't afford a newspaper?

Duh! He's got MS-NewsSim.

In the other hand, if you get the original-movie version of The Hulk on
the plane, he might open the door.

Shouldn't that air pressure push the door outwards?

Which is why it is designed to go INWARDS first, then out. The air
pressure keeps you getting the first part done. Although probably some
of it is also to break various seals.

Too much information for me. Now I will worry about the 20 tons of pressure
trying to blow the door out rather than keeping it shut... I never quite
realised that being in an aircraft was like travelling in an oxygen
cylinder -- made of thin aluminium.
