Most of the time a passenger airliner is under the control of the Avionic Expert System package, aka Automatic Pilot.  Take off is done by the flight crew.  Landing is mostly done by the AP, under control of the flight crew who have the capability of taking over or doing it all manually if the airport systems have gone off-line.

Of course, landing a plane is easy-peasy.  

Landing a plane with the passengers and crew being able to walk away is a tad more difficult.
