Air Crash Investigation: Season 15, Episode 5

15 - 5: Deadly Detour

At the height of summer in Northwestern France, the pilots of Proteus Airlines Flight 706 deviate from their flight path to go on a sightseeing detour. Determined to give their passengers a bird's eye view of a legendary French ocean liner, they fly in a low loop around Quiberon Bay. But just as they're completing a 360 around the ship, Flight 706 suddenly explodes. From a nearby airplane, a local journalist captures the scene as the wreckage falls from the sky. And as the tragedy sinks in, so does the mystery-despite thousands of eyewitnesses, no one seems to know what happened.
