WASHINGTON: Six years after the Sept 11 attacks on the United States, most Americans view the plane hijackings that killed around 3,000 people as the most significant historical event of their lives, according to a poll released on Monday.

Eighty-one per cent of those surveyed said they see the attacks as the most significant historical event of their lifetime, with more people on the east coast —90 per cent— choosing this view compared to 75 per cent on the west coast.

The Zogby International telephone poll surveyed 938 people between Sept 6 and 9 and has a three-percentage point margin of error.

The poll also showed 61 per cent of respondents saying they think of the events at least once a week and 16 per cent saying they think of the attacks every day. A full 91 per cent said they believe the United States will be attacked again on US soil.

16 per cent said they had personally visited the site of the World Trade Center in New York City to pay tribute to those who died when two passenger jets plunged into the towers and caused them to collapse.
