Video: Helicopter Shakes Itself To Pieces

A rescue helicopter has been filmed dramatically breaking apart just seconds after it landed in Brazil.

Footage showed how the aircraft shook itself to pieces - with the doors falling off - as the rotor blades continued to rotate.

Crew members remained inside the cockpit during the drama, which was captured on camera by rescue workers.

One of the crew suffered a slight foot injury but no one else was hurt in the northern state of Para.

Brazilian air accident investigators said the helicopter experienced what is known as ground resonance.

The central gear box became unstable and the resulting vibrations destroyed the aircraft.

The now-defunct helicopter belonged to the Para rescue crew.
