A flight instructor tells of the student of his who was having real trouble landing the plane, and specifically judging how close he should be to the ground before pulling up the nose of the aircraft.
Strangely enough, during the first night lesson, the student landed perfectly. Each time, just as the flight instructor thought he would have to take over, the student would pull back on the stick and make a beautiful landing.
Curious, the instructor finally asked what visual reference the student was using. Explained the student: "I just aim straight for the end-of-the-runway lights. Then I wait. When you stiffen in your seat, I pull the plane up and land."
