Deadly Exchange

S19, E1: A twin-engine turboprop carrying 15 people on a flight from St. Louis is on final approach to Kirksville, Missouri. Visibility is poor, but the pilots appear to have the runway lights in sight. Suddenly, something goes wrong. The plane crashes into a wooded area just 1.2 miles from the airport, killing all but two of the passengers aboard. It's up to the NTSB to find out what happened in the final seconds of Corporate Airlines Flight 5966. What they discover is a casual conversation in the cockpit that may have set the tone for disaster.
