Can Tenerife happen again?
The answer, is the history of what happen on 1th April 1999. Read the story here below, there is also a reconstruction of NTSB, a American organisation.
On April 1, 1999, just after 2 o'clock in the
morning, Korean Air flight 36 and Air China 9018, both Boeing 747s, nearly
collided on runway 14 Right at the Chicago O'Hare International Airport. Air
China had just landed and was rolling out on runway 14 right when the tower
controller instructed Korean Air to taxi into position and hold. After Air China
exited the runway at taxiway T10, the tower controller instructed the flight to
turn left on taxiway Kilo and cross runway 27 left. The tower controller then
cleared Korean Air for takeoff. As the airplane was rolling down the runway, Air
China deviated from its assigned taxi route and taxied on to runway 14 Right.
The Korean Air captain saw the 747 taxiing on to the runway but it was too late
to stop. Instead, Korean Air 36 lifted off earlier than normal and banked left
to avoid striking Air China. The two aircraft, carrying 382 people, missed
colliding by about 80 feet.
