I was just curious, as the plane I've flown most often as a pax is the mad dog: will the gap close up once the differential pressure goes up and the door seals press against the fuselage? do most mad dogs do this? (certainly don't remember noticing it in all my other flights) what about other planes?

When you rig a Maddog door the inital set up only measures the gap for/aft and up/down. The plane is then pressurized and you adjust the stops out until the door is flush. Many times with a new seal they are a bear to shut until it pressurizes a few times.

Just like the aft plug door on a non aft staired DC-9. I don't know how many times we have had to applied kinentic energy while at 8.0 psi Dif. ti get the door to seat right after changing a door seal.
