Other than the force of the air on the windscreen as the aircraft moves forward through the air (a function of speed and air density), the primary affect of air pressure on window glass in an aircraft is from the force of cabin air pressure pushing out against the window. This force can be in the neighborhood of 8 pounds per square inch in the average commercial aircraft. Because of this rather significant force, windows in pressurized aircraft generally are small and sturdily built.

Because the glass isn't actually a solid - it's a 'super-cooled' liquid. Since the glass is able to flex, it 'absorbs' most changes in air-pressure. This stops the glass from breaking, unless the pressure is so great or so suddent that it causes the glass to crack - creating a weakness.
