Sure, it would be difficult to land alone without the crosswinds. Really, all the pilots are doing is monitoring the landings. The heavies auto land by themselves through computer control. They intercept the ILS (instrument landing system) and the computer guides the plane completely down to touchdown.
At least this is how I assume it is. I've been flight simming for a few years now. I land the heavies all the time. Never have to touch the stick. They land themselves, as do their real counterparts. Though for fun, I do land them manually in the sim.
EDIT: From wikipedia: The output from the ILS receiver goes both to the display system (Head Down Display and Head-Up Display if installed) and can also go to the Flight Control Computer. An aircraft landing procedure can be either "coupled" (Autoland), where the Flight Control Computer directly flies the aircraft and the flight crew monitor the operation; or "uncoupled" (manual) where the flight crew fly the aircraft uses the HUD and manually control the aircraft to minimize the deviation from flight path to the runway centreline.
