It took a wild pig on the runway at Harare International Airport to reveal what many Zimbabweans have long feared: the country's Civil Aviation Authority and the national airline have gone the way of much of Zimbabwe’s other frayed institutions.

A statement from the Transport Ministry said last week that one of Air Zimbabwe’s Chinese-made MA60 60-seaters had crashed on Tuesday after hitting the bushpig — a smaller relative of the warthog — on take-off. The nose, a wingtip and a propeller were damaged.

A letter from a public-spirited passenger published yesterday in the Standard newspaper revealed that the incident was far more serious than the ministry had admitted.

Fambai Ngirande said that it was “by God’s grace” that he and the other 37 passengers and crew on board the flight to the western city of Bulawayo had not all perished. It was plain, he said, that the airline had “no disaster response strategy” and its personnel “did not have a clue” of what to do in a crisis.

“The plane was just about to lift off when we heard a loud bang from underneath followed by violent shaking of the entire aircraft,” wrote Mr Ngirande. “The aircraft veered off the runway into the grass before it came to a halt. Smoke and dust engulfed the cabin as passengers screamed for dear life.” With a petrified hostess shrieking “Evacuate!”, they discovered that one of the emergency exits was jammed. Passengers were able to jump out of the stricken plane after the main doors were laboriously opened.

The Transport Ministry had said that two people were injured “after evacuation”. This, Mr Ngirande explained, was after passengers sprinted away from the plane but crashed blindly into ditches on the dark airfield.

The airport emergency rescue service took five minutes to reach the plane. They were beaten by a contingent of secret police, whose first act was to arrest two passengers for taking photographs.

There was no medical care and it took an hour for an Air Zimbabwe manager to have water distributed. He tried to reassure them by saying that the airline’s chief executive was on his way to the airport. “The passengers retorted that they did not eat CEOs,” said Mr Ngirande.

Friends and relatives of the passengers alerted to the accident by mobile phone, gathered at the airport to find out what had happened but were told nothing and refused access, added Mr Ngirande. At midnight, five hours after the crash, the passengers were allowed to leave.

“The following morning I spoke to the two people who had been arrested,” he wrote. “They had been interrogated at length, had their cameras and tapes seized and were released at 1am.”

Mr Ngirande’s flight had been delayed by the departure of the personal jet of the Congolese President, Joseph Kabila. “It doesn't bear thinking about if the bushpig had run into Kabila’s plane,” said another passenger, who asked not to be named.
