WTC By The Numbers

The end of the World Trade Center recovery operation was marked in a solemn ceremony at the site Thursday. An honor guard of rescue workers and victims' relatives escorted an empty, flag-draped stretcher symbolizing the still-missing victims out of the seven-story pit.

The 16-acre site still contains modest amounts of debris that must be removed over the next few weeks, but the bulk of the work is complete.

Here's a look at details of the eight-and-a-half-month cleanup:

• 1,642,698 tons of debris have been removed from ground zero; 190,568 in steel.
  
• The debris has been removed in 108,444 truckloads.
  
• More than 3.1 million hours of labor were required to excavate
  the site.
  
• More than 19,500 body parts have been collected among the
  ruins.
  
• New York medical examiner has identified 1,102 victims. An
  additional 1,616 death certificates have been issued without a
  body, at the request of victims' families.
  
• New York police say 105 people are still classified as missing
  in the trade center attack.
  
• Official count of victims of the Sept. 11 terrorist attacks:

  NEW YORK: 2,823 (Includes those killed in trade center and
