This forum is probably just for commercial aircraft, but there's a lot of basic information that is useful but probably too much information for the general public.
When working on any aircraft, like the YAL-1, Boeing 747 Airborne Laser platform, emergency egress is standard training to abandon the craft if there is a fire. Of course, these procedures are easier when the craft is sitting stationary on the ground.
Generally speaking, doors on the sides of an aircraft open and swing forward. Thus, starboard doors swing to the left as one exits. And port doors swing to the right as one exits. In other words, the design intent is that the doors self close and resist opening in flight. So the next time a FA is unavailable to open the door, note that doors open different depending on which side of the aircraft you're exiting. Passenger jet bridges most often hook up to the port side.
Of course, extra doors like hatches in the cockpit are dependent on make and model of aircraft.
And then there's rear hatches and ejection seats...
