21 claims about 9/11 we've investigated in 25 years since the attacks

The 9/11 terrorist attacks, which killed nearly 3,000 people, left an indelible mark on American history — so it is perhaps unsurprising that speculation and conspiracy theories surrounding them have endured for decades. In the 25 years since the attacks, Snopes has debunked numerous rumors and examined why they persist online. For example, we disproved a false claim that the owner of the World Trade Center's Building 7 "admitted" it was destroyed in a controlled demolition rather than the terrorist attack. At the same time, we've confirmed the authenticity of some media shared online, including a photo of someone watching the Twin Towers burn. Below are 21 claims about 9/11 that we've investigated over the years. Sources "9/11 Investigation." History, FBI, https://www.fbi.gov/history/famous-cases/911-investigation.MacGuill, Dan.
