Passengers bound for the Taiwanese Kinmen islands received a horrifying shock as they watched their plane's engine cover broke apart in midair.

Shocking footage shows the metal panel of the ATR 72-600 aircraft flapping violently, exposing the internal engine components.

The incident occurred shortly after takeoff from Kaohsiung International Airport this morning.

Those onboard the flight were initially alarmed when the plane began to shake from the issue with the turbopropeller engine.

Looking out of the windows, they were stunned to see the engine cover coming loose, bending upwards and downwards under strong air currents.
