ATTA, Mohamed

Born in Kafr el-Sheikh, Egypt, Atta studied architecture at Cairo University before receiving a scholarship to pursue graduate studies in urban planning at Hamburg University of Technology in Germany. It was in Hamburg that he became radicalized and joined the al-Qaeda cell that would form the core of the 9/11 operation, along with Ramzi bin al-Shibh, Marwan al-Shehhi, and Ziad Jarrah.

Atta’s transformation from secular student to Islamic extremist occurred gradually during his time in Hamburg, influenced by radical clerics at the Al-Quds Mosque and exposure to jihadist literature and videos. By 1999, he had established contact with al-Qaeda operatives and traveled to Afghanistan for training at terrorist camps, where he was selected by Osama bin Laden to lead the “planes operation.”

The FBI’s investigation revealed Atta’s meticulous preparation for the attacks, including flight training at Huffman Aviation in Florida, surveillance of potential targets, and coordination with other hijacker cells. He made several trips to Europe and the Middle East to receive instructions and funding, maintaining contact with al-Qaeda leadership through encrypted communications and coded messages.

Surveillance footage from multiple airports captured Atta’s movements on September 11, 2001, as he traveled from Portland, Maine, to Boston’s Logan International Airport with fellow hijacker Abdulaziz al-Omari. Security cameras recorded them passing through airport security and boarding American Airlines Flight 11, which Atta piloted into the World Trade Center’s North Tower at 8:46 AM.

Contrary to some disputed claims, investigations by the CIA, FBI, and 9/11 Commission found no credible evidence supporting allegations that Atta met with Iraqi intelligence officers in Prague before the attacks. These claims, promoted by some officials seeking to link Iraq to 9/11, were thoroughly investigated and rejected by intelligence agencies as unsubstantiated.

Atta’s personal effects, recovered from luggage that failed to transfer to Flight 11, included a handwritten letter containing religious instructions for the hijackers, providing insight into the attackers’ mindset and religious justifications for their actions. The document became key evidence in understanding al-Qaeda’s operational methods and ideological motivations.
