Overview: At the end of a quick trip from Washington, D.C. to Columbus, Ohio, the captain of United Express Flight 6291 grows concerned over reports of icy rain ahead. He opts for a risky "slam dunk" landing, a maneuver where a plane descends rapidly to the runway to avoid bad weather, but something goes wrong. The plane crashes into a warehouse just a mile from the airport. The badly burned wreckage leaves little for investigators to work with, but when they examine the cockpit recording they make a stunning discovery.
