Sept. 11 Marked With Moment of Silence Lead by President, Other Ceremonies

(Fox News) - President Bush led a moment of silence at the White House Thursday and other ceremonies were taking place in New York and Pennsylvania in honor of the 3,000 people who died Sept. 11, 2001, in the worst terrorist attack on American soil.

The ceremony on the South Lawn occurred at 8:46 a.m., the time that terrorists flew the first commercial jetliner into one of the Twin Towers of World Trade Center. The second plane crashed into the other tower at 9:03 a.m.

In New York, four moments of silence were happening Thursday morning to commemorate the precise times that two hijacked jetliners crashed into the World Trade Center, along with the times that each tower collapsed.
