control of pilot on the yoke but turning the heading in which case the computer would still be flying the plane, autopilot under control and hit those way opponents we talked about perfectly. could you show us how that would work? >> go ahead, tell us. >> the autopilot is controlled through this panel. we call this the remote control panel. all it is, the number you see here is heading. degree magnetic this is compass, cartesian points, north, east, south, west. all you have to do is turn the nobody and the airplane will turn that direction. >> feel it now. it's being done automatically. nobody touching the yokes. it's done smoothly. if you're a passenger, you can make it turn significantly without spilling a drink or making sure something is wrong. >> let me ask a follow-up.
