Trivia
According to John Romero, "The only way you are supposed to reach the secret switch [inside the blue box at the north end of the map] was by (1) getting the invincibility, (2) blasting a rocket into the wall so you would fly backwards into the box. We found out early on that it was possible to flip the switch from outside, so Sandy made the walls thicker." (See Doom Level History.) In fact, it is still possible to activate the switch from just outside of the walls, and also to straferun-jump into the box. See Access the secret exit on level E3M6 for details.
