Airbus submits patent application for windowless jet cockpit | Ars Technica
Whoever filed the patent seems to think you could put the cockpit anywhere in the aircraft. I don't think they have considered the acceleration forces on the crew in some of these positions.
Throwing the crew around in their "cockpit" is one way to initiate a PIO!
I'd be interested to know how they expect to avoid the occasional non-squawking object one encounters.
