“would not be in that position”?!? What version of reality are you smoking where these seats are gonna freaking move to vertical?
Edit: on further inspection, you’re gonna go full ATM if you sit upright. You’re so low to the floor to accommodate the upper decker that your knees would be in your chest cavity if they were on the floor. Frack every bit of this idea in the neck, sideways, with a screwdriver.
Have you ever been in an airliner? “upright an locked in their vertical positions” - ever heard that? Putting goddamned laz-e-boys in the middle of an airliner is gonna lead to corpses in the event of a catestrophoc accident. (not that it would stop the airline industry, if it could)
