A door that is adapted to separating two environments with different pressures and to an aircraft with such a door. The door may include a door leaf, a door frame having a door stop and a roller, and an actuating system having a latch element and an inward-moving drive system. The inward-moving drive system may include a puller shaft and a puller that is non-rotatably attached to the puller shaft. The puller may include a guide rail that moves along the roller during a rotation of the puller such that the puller moves the door leaf in direction of the first environment thereby disengaging the latch element from the door stop.
