As for video technology, suppose that fails. Then what. Also, where below the floor would you put it. In the nose? You have the nose gear there. In the middle? Not only do you have the main gear and the fuel tanks there, but you also sacrifice cargo space. In the back?

But, with advances in fly by wire and enhanced video, is there any reason cockpits need to remain in the nose of the aircraft? I'm not suggesting remote control or anything like that, but is it practical to consider below the floor or other options to open up seating capacity or other amenities?

Any particular case when front of the aircraft was affected, but not the back? I can think of one..
And extra 0.1 second in case of crash makes little, if any, difference. Only to jump the line to St. Peter, maybe..
On a more serious note - as far as I understand all current FBW airliners have limited mechanical control fallback as measure of last resort, so total loss of power is one of the things planned for - and that excludes any cockpit location without direct view of future crash location.

Airbus FBW airplanes have a (very limited) backup system, which (on A320, newer models might be different) includes the Rudder the Stabilizer Trim (but no Elevator or Ailerons) - but even though it is called "Mechanical Backup" it requires at least one hydraulic system to be operative (without hydraulics the only possibility to control the aircraft is through thrust changes - assymetric thrust for turns, increasing thrust to climb and reducing thrust to descend). It is designed to cover a temporary full electrical failure or the temporary loss of all flight control computers. I think Airbus test pilots demonstrated that a landing can be performed in mechanical backup (in very benign conditions, I assume) during the flight test campaign, but it was never intended to be used for landing - only to keep the aircraft in an acceptable attitude long enough to hopefully recover some electrics/flight control computers. We tried it in the simulator - the aircraft can indeed be maintained in a more or less controlled condition and with some practice it is possible to do climbs/descend and turns, however it I think its a matter of luck of being able to land the airplane in this condition.
I am not sure as I am not familiar with Boeing systems, but I think the 777 backup system also requires some hydraulics to be functioning, maybe somebody familiar with the Boeing system can confirm?
