12 Pages and noone has even touched on how you could ever certify a pilotless pax aircraft. The efforts required to prove the redundancy plus the test flying would almost be not worth it. Then once you've done that someone has to insure it. All that's assuming you had the technology available to do it in the first instance. The cost of the redundancy would also be an issue to consider.
Some of these tech guys on here have a website mentality to these things in that you build a half arsed product get it out to market ASAP then iron out the bugs later on. Can't do that in aviation i'm afraid.......Mind you Boeing had a good crack it with the 787!
