MH370: US Intel Assessment Suggested That Plane Deliberately Taken Off Course, Source Says

The source cautioned that the assessment is of very little value.

However, according to the source, the assessment "doesn't matter" and was built on information that intelligence officials could glean about the foreign investigation in the disappearance.

The revelation comes as investigators were trying to piece together whether an airplane part that washed up on the shore of Reunion Island came from the doomed flight.

Based on a part number that was visible in pictures, Boeing workers believe it came from a 777, the same type of plane as MH370, according to a US official.

In the wake of the discovery, a worker found a tattered piece of luggage on the same beach.

The origin of the piece of luggage has not been determined, but it was seized by local police for examination.

Investigators were treating the airplane part, believed to be a "flaperon," as a major lead into the disappearance of the plane.

Flaperons help to stabilize the plane, especially at low speeds such as takeoff and landing.
