Korean Air Flight 801 crashed in Guam when the pilot focused on an incorrect instrument landing signal. This caused the plane to crash into the side of a mountain instead of following the glideslope instrument landing system that the pilot thought was operational on the runway. So when a plane picks up the wrong signal, bad things can happen. What is the instrument landing signal that we're supposed to pick up and keep our eyes focused on?
