Re: Possibility of the 797 having a T-Tail?

On a -200, the aft stairs acted as a “tail pole” in case the aft baggage was loaded first.

Wing mounted engines also allow for fitting engines of different weights from different engine manufacturers because the heavy component is near the CofG.

Re: Recovery of Hand Luggage After Emergency Evac

Its an emergency whenever the captain or the fire scene commander says it is an emergency. Not your call, not mine except when being the captain.
