Upon completion, One World Trade Center in New York City surpassed the Willis Tower through its structural and pinnacle heights, but not by roof, observation deck elevation, or highest occupied floor. Until 2000, the tower did not hold the record for being the tallest building by pinnacle height. From 1969 to 1978, this record was held by John Hancock Center, whose antenna reached a height of , taller than the Sears Tower's original height. One World Trade Center became taller by pinnacle height with the addition of a 359-foot (109.4-meter) antenna, bringing its total height to . In 1982, two antennas were installed which brought its total height to , making it taller than the John Hancock Center but not One World Trade Center.

A thick fog settled in near the end of his climb, making the last 20 stories of the building's glass and steel exterior slippery.
