even if you are in a nice jet, with multiple engines, there may be a time you have to land off airport
so always have a field, open area, road, waterway etc in mind on which to land.
and as you travel across country, be thinking ahead to the next emergency landing spot.
a plane may catch fire (think swiss air, value jet, UPS) and getting down anywhere might save lives.
all engines may quit
and the person who indicated a flight doesn't end till you taxi to parking and shut down the engines....that's fine, but you might make sure the parking brake is set and the chocks are in place.
