Atterraggio d'emergenza

B747 flight deck is on the 1st floor, going upstairs !! Yet, all characters (good / bad) walk through some "curtains" at the front of the First Class area (before the B747 nose with enclosed radar) and pass through abundant "open space" (including toilet cubicles !!) to reach the cockpit.

Several exterior views of the B747 (extended "hump" on upper section) and winglets) suggest a B747-400 series aircraft, and this B747 has only 2 flight crew (Captain and First Officer, NO Flight Engineer), as expected, but the spiral staircase inside the cabin, behind First Class, is found in B747-100 and B747-200 series aircraft (NO extended "humps"). B747-300 and B747-400 series aircraft wth extended "humps" have straight staircases rising to the opposite side of their respective cockpits.
