In August 24, 2001, an Air Transat Airbus A330, heading from Toronto, Canada to Lisbon, Portugal, experienced problems with the left engine's fuel supply. Hours later, the plane runs out of fuel over the Atlantic and has to glide to a landing without power. National Geographic Air Emergency explores the causes that contributed to this catastrophe and shows how the crew managed to glide to a landing without fatalities or injuries.

August 14, 2005, a Helios Airways 737 crashed in Greece, killing all 121 people on board. The exact cause of the crash was unknown, but aviation experts speculated that the plane's cabin pressurization system failed early in the flight. It was assumed that everyone on board lost consciousness while the plane continued to fly on autopilot until it ran out of fuel. More recent analyses suggest that at least two flight attendants were able to stay conscious using portable oxygen bottles, but that they were unable to open the reinforced cockpit door in time.
