Just read this short article about two Britons trying to open one of the plane's doors during a flight to Manchester.

--> What would happen if the two women succeded in opening the door?

Answer 1

I believe the rush of air pressure would suck the first 10 rows out of the plane.

Answer 2

Um oxygen mask would come down your ears would pop ! Lose items would fly out and people with out seat belts on could too !
