When it opened last year, many people praised the futuristic structure, calling it both beautiful and practical. Since there were no internal roof supports, passengers could move easily through the terminal. Some engineers say that the terminal's tunnel shape may have been a factor in the collapse. Buildings with no internal supports must rely entirely on the outer shell. However, investigators point out that it is the role of engineers to assure the safety of an architect's designs. Leslie Robertson, a chief engineer of the World Trade Center towers, told the New York Times that when problems occur, it's usually in the "interface" between architects, engineers, and contractors.
The collapse killed several people and left a 50 by 30 meter hole. It will take many months, and perhaps years, for investigators to determine whether the fatal collapse was caused by design flaws or oversights in construction. Meanwhile, airport officials say that they may tear down the terminal rather than repair it.
