Q: American Airlines Flight 11: FAA Awareness. Although the Boston Center air traffic controller realized at an early stage that there was something wrong with American 11, he did not immediately interpret the plane's failure to respond as a sign that it had been hijacked. At 8:14, when the flight failed to heed his instruction to climb to 35,000 feet, the controller repeatedly tried to raise the flight. He reached out to the pilot on the emergency frequency. Though there was no response, he kept trying to contact the aircraft. At 8:21, American 11 turned off its transponder, immediately degrading the information available about the aircraft. The controller told his supervisor that he thought something was seriously wrong with the plane, although neither suspected a hijacking. The supervisor instructed the controller to follow standard procedures for handling a "no radio" aircraft. The controller checked to see if American Airlines could establish communication with American 11. He became even more concerned as its route changed, moving into another sector's airspace. Controllers immediately began to move aircraft out of its path, and asked other aircraft in the vicinity to look for American 11. At 8:24:38, the following transmission came from American 11: American 11: We have some planes. Just stay quiet, and you'll be okay. We are returning to the airport. The controller only heard something unintelligible; he did not hear the specific words "we have some planes." The next transmission came seconds later: American 11: Nobody move. Everything will be okay. If you try to make any moves, you'll endanger yourself and the airplane. <sep>What were the first things done by America 11 that led the air traffic controller to notify his supervisor that something was wrong with the flight?<sep>There was no response

A: No

Q: Little is known of the earliest Stone Age inhabitants of Europe's southwestern extremity. The ancient Greeks called them the Cynetes (or Cunetes). Whatever their origins, their culture evolved under the pressure and influence of foreign forces. Among the many invading armies that settled here and contributed to nascent Portuguese culture were Phoenicians, who settled in the area around 1,000 b.c., followed by the Celts, Iberians, Greeks, and Carthaginians. But it was the Romans, who arrived late in the third century b.c., who most greatly influenced all of Iberia. They built towns, industries, roads, and bridges, developed agriculture, and bequeathed the Latin language, of which Portuguese is a direct descendant. The Romans named the southwestern province of the peninsula Lusitania, oddly enough for one of the Celtiberian tribes they defeated, and by the third century a.d. had introduced Christianity. By the beginning of the fourth century the Algarve had a bishop in place, based in Faro. But Rome had already fallen into decay, and soon hordes of northern tribesmen took over the empire. The Algarve fell to the Visigoths in the mid-fifth century. Under Moorish Rule In a.d. 711, the Moors brought powerful armies from North Africa and launched a devastating attack on the Iberian peninsula, conquering much of what would become Spain and Portugal. They imposed Islam and left an indelible influence on the countryside and the population of the Algarve. The Moorish legacy can still be seen in the form of wells and waterwheels, squat white houses, the dark complexions of the people, and in the very name given the region — taken from Al-Gharb, which means "country of the west" (when the Moors conquered the territory, it was the most westerly in the known world). The Moors governed their Iberian kingdoms from across the border in Seville, but the Algarve had its own regional capital and huge, invulnerable fortress. The capital was Chelb (or Xelb), and it was bigger and better defended than Lisbon. Today the town, known as Silves,  is a provincial outpost whose only besiegers are busloads of tourists who climb the narrow streets up to the old Moorish ramparts. <sep>What was the Portuguese city of Silves was once known as?<sep>The Cynetes (or Cunetes)

A: Yes

Q: The Bush administration did not develop new diplomatic initiatives on al Qaeda with the Saudi government before 9/11. Vice President Cheney called Crown Prince Abdullah on July 5, 2001, to seek Saudi help in preventing threatened attacks on American facilities in the Kingdom. Secretary of State Powell met with the crown prince twice before 9/11. They discussed topics like Iraq, not al Qaeda.U.S.-Saudi relations in the summer of 2001 were marked by sometimes heated disagreements about ongoing Israeli- Palestinian violence, not about  Bin Laden. The confirmation of the Pentagon's new leadership was a lengthy process. Deputy Secretary Wolfowitz was confirmed in March 2001 and Under Secretary of Defense for Policy Douglas Feith in July. Though the new officials were briefed about terrorism and some of the earlier planning, including that for Operation Infinite Resolve, they were focused, as Secretary Rumsfeld told us, on creating a twenty-first-century military. At the Joint Chiefs of Staff, General Shelton did not recall much interest by the new administration in military options against al Qaeda in Afghanistan. He could not recall any specific guidance on the topic from the secretary. Brian Sheridan-the outgoing assistant secretary of defense for special operations and low-intensity conflict (SOLIC), the key counterterrorism policy office in the Pentagon-never briefed Rumsfeld. He departed on January 20; he had not been replaced by 9/11. Rumsfeld noted to us his own interest in terrorism, which came up often in his regular meetings with Tenet. He thought that the Defense Department, before 9/11, was not organized adequately or prepared to deal with new threats like terrorism. But his time was consumed with getting new officials in place and working on the foundation documents of a new defense policy, the quadrennial defense review, the defense planning guidance, and the existing contingency plans. He did not recall any particular counterterrorism issue that engaged his attention before 9/11, other than the development of the Predator unmanned aircraft system. The commander of Central Command, General Franks, told us that he did not regard the existing plans as serious. To him a real military plan to address al Qaeda would need to go all the way, following through the details of a full campaign (including the political-military issues of where operations would be based) and securing the rights to fly over neighboring countries. The draft presidential directive circulated in June 2001 began its discussion of the military by reiterating the Defense Department's lead role in protecting its forces abroad. <sep>Who wanted to secure the rights to fly over neighboring countries<sep>Bush

A:
No
