i know the knowledgeable people in this forum will respond correctly to my query:
someone recently posted this and i am wondering how accurate it is.
thanks for any clarification.

Airplane doors look like they open outwards when you see the airplane on the ground, but that’s the effect of a complicated mechanical linkage. The door actually opens inwards first, before the linkage will move the door to the outside. It is physically impossible for a human to open it against the pressure [when in flight].

There are a lot of different aircraft with a lot of different doors. But yes, some do open inwards first.

757-200 door opening inwards first, then outwards.
