Staff lie on the runway at Ben Gurion International airport near Tel Aviv during an emergency drill. Here police officers play the role of passengers in a simulated crash by a 747-400 after a failed emergency landing -- a catastrophe that could claim around 200 lives. Authorities burned tires and scrap metal to create realistic levels of smoke and fire. Some 1,500 people were involved in the annual safety exercise, which was made more complicated this year by the closure of two runways for renovation.
