It was 7:30 P.M. on June 1, 2009. No one on board thought anything could go wrong on this Rio to Paris flight.

However, things did not go to plan.

In a few hours, the A330 would be part of a three year-long investigation. It was four hours later when a gauge indicated that there was a rise in temperature. That was nothing that pilots Marc Dubois and David Robert were worried about. But that was only the beginning of the disaster.

An alarm lit up. Suddenly, autopilot and several instruments shut down by themselves. The pilot in control pulled up. The plane stalled and started a descent in a level position.

At 9:10 A.M. local time, the expected time of arrival, Flight 447 was nowhere in sight. The plane, Air France Flight 447, crashed.

There are two questions: Where is it? And what happened to Airbus A330?

Answers seemed to be gone with the plane.

Forever.
