Based on my observations as a mere passenger, it seems to me that
airline pilots do their crosswind landings using crab
and then step on the rudder to straighten out the plane just before
touchdown.

Is this how it's done? Why wouldn't they slip the plane?
Sometimes, the landing gear gets a significant side load on touchdowns
which is the reason why I'm asking.

Oh, while you're here: If they do a rectangular traffic pattern, what is
the typical size and altitude of it?
