Architect Minoru Yamasaki had designed the World Trade Center towers to withstand a colliding jetliner. But 30 years after the construction of the towers, jetliners have grown in size.
"Built to withstand earthquakes and hurricane-force winds, and equipped with enhanced security after a 1993 terrorist bombing, the twin towers of New York's World Trade Center were supposed to last. Their architect boasted that they could withstand the impact of a jumbo jet...Experts agreed that collapse of the two towers was almost inevitable; although their "tube structure" design was their greatest source of strength, it was also an Achilles' heel. For someone who wanted to bring them down, a guided missile filled with jet fuel was perhaps the only way."
