Mayday S05E09 - Fatal Distraction

On 29 December 1972, Eastern Air Lines Flight 401 is on a flight to Miami International Airport. While making preparations to land, the crew is distracted by a faulty landing gear indicator light and accidentally disengages the autopilot while trying to resolve the problem. The aircraft descends until it crashes into the Everglades. Flying at night, the crew failed to notice their descent until only seconds before hitting the ground. 101 people died; 75 people survived.
