One of the big pushes in aviation and military is that the common cockpit designs, which are ergonomically correct. The common cockpit Initiative (CBI) means all aircraft have basically the same cockpit, all instruments are in place, the seats in the same place, in fact almost everything that would be the same. This would make the virtual reality simulation training, easy and allow maximum efficiency and save lives, as the human element should never be confused and thus fewer mistakes would be made in family cabins under extreme stress during incidents, under fire or during equipment failure. This would allow maximum use of the unity of "human" like everyone else could do the job. In the extreme, this would mean your car or commercial truck would be similar to anti-war tank, airliner, private boat, fighter aircraft, helicopters and buses. Engineers often laugh at this saying, "Oh, of course, and the bureau also aims well, once it takes a download simply move the joystick down indicating the toilet to release the human waste and color? "Then another engineer laughs and says," Yah or it could be a leveler identical to the "Bombs Away" switch in a fighter-bomber carrying ammunition smarter?
