Vibrations on touchdown would be nice too, I often have difficulties identifying if I’m on the ground or still in the air while landing, especially in bigger aircraft.
I hope it’s the -900. It’s seems as though we’ve got the longest versions of the airliners like the 78X, 773, 739, a321 it would be nice to have a more compact airliner if that makes any sense(does in my head) me personally a 789 or 8 and a 772…
