September 2, 1998. Swissair Flight 111 leaves New York's JFK Airport for Geneva, Switzerland. Less than an hour into the flight, the pilots smell smoke and prepare for an emergency landing in Halifax. But minutes later, an inferno erupts in the cockpit, sending the MD-11 into the Atlantic Ocean, killing all 229 on board. Witness the flight's final moments, then follow the largest disaster investigation in Canada's history-a four and a half years, $40 million inquiry-to uncover why such a highly reliable plane suddenly burst into flames.
