Each episode aims to explain a single incident by analyzing the causes and circumstances that ultimately affected the disaster.
British Midland Flight 92, a two-month-old Boeing 737-400, takes-off from Heathrow Airport in London, heading for Belfast.
The crew shut down the wrong engine and start to prepare for an emergency landing at East Midlands Airport.
For days, a foul smell hangs around in the Humberto Vidal shoe store in San Juan, Puerto Rico.
The smell is caused by leaking propane gas coming from an unmapped pipe in the sloping road near the shoe store.
Then, an air conditioner with bad wiring is switched on, starting a spark that ignites the propane and the store explodes, claiming 33 lives.
Although the submarine has explosion-proof walls, the explosion spreads through the ventilation shafts, killing everyone at the command post and preventing the sub from performing an emergency blow.
While the survivors wait to be rescued, special boards that produce breathing oxygen with potassium superoxide drop into the oily floor, starting a reaction that creates a fire, killing them as well.
Suddenly a fire starts in the cabin and cockpit, so large it consumed in flames and the crew are incapacitated by the smoke.
A de Havilland DH.106 Comet 1, the world's first passenger jet airliner, takes off from Rome but explodes over the Tyrrhenian Sea 26 minutes into the flight, killing all 35 people on board.
The investigation results in improved metallurgical understanding, from which all aircraft design greatly benefits, even over five decades after the incidents.
A team of meteorologists led by Ted Fujita will examine the tragedy to provide new methods to predict more precisely the future tornadoes.
