Of the 2,606 victims killed inside the World Trade Center and on the ground in New York City during the September 11 attacks, some have estimated that at least 200 people fell or jumped to their deaths, while other estimates put the number around 100. Officials could not recover or identify the bodies of those forced out of the buildings prior to the collapse of the towers. The New York City medical examiner's office said it does not classify the people who fell to their deaths on September 11 as "jumpers". These people were forced out by the smoke and flames or blown out.
