. The family had few relatives on the father's side and kept their distance from Buthayna's family. In-laws characterized Atta's father as "austere, strict, and private", and neighbors viewed the family as reclusive. Atta was the only son; he had two older sisters who are both well-educated and successful in their careers – one as a medical doctor and the other as a professor. When Atta was ten, his family moved to the

. Atta also got engaged to a woman lined up by his father and her family in Cairo, in late 1999, after coming back from Germany the same year. Although the marriage never happened, Atta's father said they liked each other.

Atta graduated from Cairo University with marks insufficient for the graduate program. As his father insisted that he go abroad for

Atta accepted and arrived in Germany two weeks later, in July. In Germany, he enrolled in the

s, socializing seldom, and acting disdainfully towards the couple's unmarried daughter who had a young child. After six months, they asked him to leave. By early 1993, Atta had moved into university housing with two roommates, in Centrumshaus. He stayed there until 1998. During that period, his roommates grew annoyed with him. He seldom bathed, and they could not bear his "complete, almost aggressive insularity". He kept to himself to such an extent that he would often react to simple greetings with silence.


Academic studies

At the Hamburg University of Technology, Atta studied under the guidance of the department chair, Dittmar Machule, who specialized in the Middle East. Atta was averse to modern development. This included the construction of

s in Cairo and other ancient cities in the region. He believed that the drab and impersonal apartment blocks, built in the 60s and 70s, ruined the beauty of old neighborhoods and robbed their people of privacy and dignity. Atta's family moved into an apartment block in 1990; it was to him but "a shabby symbol of Egypt's haphazard attempts to modernize and its shameless embrace of the West." For his thesis, Atta concentrated on the ancient Syrian city of

. Atta's professor, Dittmar Machule, brought him along on an archaeological expedition to Aleppo in 1994. The invitation had been for a three-day visit, but Atta ended up staying several weeks that August, only to visit Aleppo yet again that December. While in Syria, he met Amal, a young

woman who worked for a planning bureau in the city. Volker Hauth, who was traveling with Atta, described Amal as "attractive and self-confident. She observed Muslim customs, taking taxis to and from the office so as not to come into close physical contact with men on buses. But she was also said to be 'emancipated' and 'challenging'. Atta and Amal appeared to be attracted to each other, but Atta soon decided that "she had a quite different orientation and that the emancipation of the young lady did not fit." His nascent infatuation with her, begrudgingly realised, was the closest thing Atta knew to romance. In mid-1995, he stayed for three months in Cairo, on a grant from the Carl Duisberg Society, along with fellow students Volker Hauth and Ralph Bodenstein. The academic team inquired into the effects of redevelopment in the

. Atta stayed in Cairo awhile with his family after Hauth and Bodenstein flew back to Germany. While in Hamburg, Atta held several positions, including a part-time job at the urban planning firm Plankontor beginning in 1992. He was let go from the firm in 1997, however, because its business had declined and "his draughtsmanship was not needed" after it bought a CAD system. Among other odd jobs to supplement his income, Atta sometimes worked at a cleaning company and sometimes bought and sold cars. Atta had harbored a desire to return to his native city ever since he finished his studies in Hamburg, but he was prevented by the dearth of job prospects in Cairo, his family lacking the "right connections" to avail the customary

. Further, after the Egyptian government had imprisoned droves of political activists, he knew better than to trust it not to target him too, with his social and political beliefs being such as they were.


Religious zeal and Hamburg cell

After coming to Hamburg in 1992, Atta grew more religiously fanatical and frequented the mosque with greater regularity. His friends in Germany described him as an intelligent man in whom religious convictions and political motives held equal sway. He harbored anger and resentment toward the U.S. for its policy in Islamic nations of the Middle East, with nothing inflaming his ire more than the

After leaving Plankontor in the summer of 1997, Atta disappeared again and did not return until 1998. He had made no progress on his thesis.

By mid-1998, Atta was no longer eligible for university housing in Centrumshaus. Atta, Bahaji and Ramzi moved into a Hamburgian apartment, which they supposedly named . By early 1999, Atta had completed his thesis, and formally defended it in August 1999. In mid-1998, Atta worked alongside Shehhi, bin al-Shibh, and Belfas, at a warehouse, packing computers in crates for shipping. The Hamburg group did not stay in Wilhelmsburg for long.

It is not known if the 19 names were all those of the hijackers who would carry out the 9/11 attacks or if the list length is just a coincidence.

reported that the cockpit was unresponsive and inaccessible. At 8:24:38 a.m., a voice believed to be Atta's was heard by air traffic controllers, saying: "We have some planes. Just stay quiet and you will be OK. We are returning to the airport." Evidently, he tried to deliver a message over the cabin's PA system instructing the passengers and crew to stay put, but pressed the wrong switch and thereby tipped off ATC that the flight had been hijacked. Seconds later he transmitted another message: "Nobody move, everything will be OK. If you try to make any moves you'll endanger yourself and the airplane. Just stay quiet." About a minute later, he turned the plane southbound, on a course pointed in the direction of New York City. Atta was not heard from again for nine minutes until 8:33:59 when he transmitted, "Nobody move, please. We are going back to the airport. Don't try to make any stupid moves." This was the last transmission from Flight 11. Twelve minutes later, at 8:46:40 a.m., Atta crashed the plane into the North Tower of the World Trade Center in New York City between floors 93 and 99, killing himself and everyone else aboard the plane. Hundreds more inside the North Tower were also killed instantly, while the damage Atta had done to the building severed all escape routes from Floor 92 and higher, trapping more than 800 survivors of the crash in the upper floors of a burning quarter-mile high skyscraper, thus ensuring that no one above the 91st floor was able to make it out alive before the tower collapsed 102 minutes later at 10:28 a.m. Because the flight from Portland to Boston had been delayed, Atta's luggage did not make it onto Flight 11. His bags were later recovered in Logan International Airport, and were found to have contained airline uniforms, flight manuals, and other items. The luggage included a copy of Atta's will, written in Arabic, as well as a list of instructions, called "The Last Night". This document is divided into three sections; the first is a fifteen-point list providing detailed instructions for the last night of a martyr's life, the second gives instructions for travelling to the plane and the third from the time between boarding the plane and martyrdom. Almost all of these points discuss spiritual preparation, such as prayer and citing religious scripture.


Family reaction and denial

Shaffer largely based his allegations on the recollections of Navy Captain Scott Phillpott, who later recanted his recollection, telling investigators that he was "convinced that Atta was not on the chart that we had." Phillpott said that Shaffer was "relying on my recollection 100 percent," and the Defense Department Inspector General's report indicated that Philpott "may have exaggerated knowing Atta's identity because he supported using Able Danger's techniques to fight
