Last minutes before landing at Rockford ILL. Here we answer the question of what it is like on a bad day. Pilot cannot think far enough ahead of the aircraft approach is sloppy or speeds are off or if you can walk away from a landing it is a good one. A bad day still has to be safe. Here I blew the approach high on the glide slope this would be an automatic miss but got her on anyway. We learn from our mistakes or we read about them.
