THIS is the shocking moment emergency crew rushed to a plane after a passenger allegedly attacked a flight attendant and leapt out of the aircraft.

The horror incident saw this flyer plunge 11.5 feet to the crowd after forcing the emergency door open.

This shock incident took place when Iberia flight IB578 attempted to depart out of Paris Orly Airport, in France, around 5.20pm on Friday.

The passenger suddenly got up from his seat as the flight was taxiing for takeoff.

He made his way to the front of the cabin where he allegedly tried to open the emergency exit.

A flight attendant intervened, but was allegedly assaulted before the passenger successfully opened the door.

The passenger plunged to the tarmac while the Airbus’ engines were still running.

This plane was due to fly to Barajas Airport in Madrid, Spain.

Dramatic footage showed emergency crews rushing to the aircraft to stop the rogue passenger.

A video caught by a flyer on the plane, showed several police cars, with flashing lights on, as they rushed to the scene.

The flyer was detained on the tarmac.

His current condition and the reasons for his outburst are currently unclear.

Despite the seriousness of the situation, the flight still departed for Madrid later that evening.

The aircraft arrived in Madrid just before midnight after a delay of four and a half hours.

The three-year-old plane was then temporarily taken out of service before resuming operations on Saturday afternoon.

An investigation into the shock incident has been launched.

It was the second time in three months that a passenger had opened an emergency exit before take-off on an Iberia flight, as reported by NeedToKnow.

A nervous passenger deployed an emergency slide just as the Iberia Express flight was about to depart Ibiza for Madrid in December.

On that occasion, cabin crew members were able to stop the traveller from leaping down the slide.
