Linked by a bridge at the 41st and 42nd floors, the Petronas Towers rise 1,483 feet off the ground, but they are only 88 stories. Thus though they squeak past the Sears Tower in Chicago by 33 feet, the Sears Tower can still claim the highest occupied floor (110 stories). The World Trade Center, which was built in the early 1970s, was the world's tallest only briefly--until the Sears Tower was erected in 1973. New York loyalists insisted, however, that when the Trade Center's antenna was included in the measurement, it still retained its world's-tallest status. Now, of course, that's a moot point, and all other such wrangling should halt for some time if the Center of India Tower planned for Katangi, India, goes up as planned in 2008. It will be 2,222 feet tall.
