Re: Boeing 797 Discussion Thread - 2018

Average cabin width (without 20 inch aisle(s)) at shoulderheight per passenger would have my preference. Sidewall shape, armrest number/ width, aislewidth give too much opportunity for creativity / perception management with seat(bottom, cushion)width.

The C-17 eats the semi unprepared run way, preventing further utilization. Because of its mass. That's why the USAF avoids that when possible. The aircraft gets easily damaged and you want flight hours down/ used when neccesary only.
