A London-bound British Airways plane crashed into a building as its crew prepared to take off from Johannesburg, South Africa, on Sunday.

The aircraft was carrying around 180 passengers at O. R. Tambo International airport when its wing sliced into the top floor of a brick building, South Africa’s airport authority has confirmed.

No one was seriously injured, but four employees who were in the building at the time sustained minor injuries.

A spokesman for the airport confirmed the plane had been damaged and said all passengers were being taken off the flight to spend the night in a hotel.

On its Twitter page, the airline responsible for the plane said: “One of our aircraft was damaged whilst taxiing at JNB airport. All 182 passengers disembarked safely with no injuries onboard.”

Harriet Tolputt, the head of media for Oxfam, was on the flight when the crash happened.

She wrote on Twitter: “BA plane crashes into building at J Burg airport. No one injured only the pilot’s pride.”

The plane was taxiing when she heard a very loud crash and watched as the plane collided with the structure at the edge of the runway, she told NBC News.

The Boeing aircraft has now been moved, and Airports Company South Africa (ACSA) is currently investigating the incident.
