“ The landing is made to the right, parallel with the lights. The Captain circled the landing area during his descent, found the line of lights properly placed into the wind, and received a green flare from the launch, indicating that the area was clear of obstructions. At an altitude of approximately 500 feet, he lined the aircraft up with the lights for a final approach and started a descent at a rate of 300 feet per minute and 90 knots indicated air speed, with full flaps. ”
