Q: According to the radar reconstruction, American 77 reemerged as a primary target on Indianapolis Center radar scopes at 9:05, east of its last known position. The target remained in Indianapolis Center's airspace for another six minutes, then crossed into the western portion of Washington Center's airspace at 9:10. As Indianapolis Center continued searching for the aircraft, two managers and the controller responsible for American 77 looked to the west and southwest along the flight's projected path, not east-where the aircraft was now heading. Managers did not instruct other controllers at Indianapolis Center to turn on their primary radar coverage to join in the search for American 77. In sum, Indianapolis Center never saw Flight 77 turn around. By the time it reappeared in primary radar coverage, controllers had either stopped looking for the aircraft because they thought it had crashed or were looking toward the west. Although the Command Center learned Flight 77 was missing, neither it nor FAA headquarters issued an all points bulletin to surrounding centers to search for primary radar targets. American 77 traveled undetected for 36 minutes on a course heading due east for Washington, D.C. By 9:25, FAA's Herndon Command Center and FAA headquarters knew two aircraft had crashed into the World Trade Center. They knew American 77 was lost. At least some FAA officials in Boston Center and the New England Region knew that a hijacker on board American 11 had said "we have some planes." Concerns over the safety of other aircraft began to mount. A manager at the Herndon Command Center asked FAA headquarters if they wanted to order a "nationwide ground stop." While this was being discussed by executives at FAA headquarters, the Command Center ordered one at 9:25. The Command Center kept looking for American 77. At 9:21, it advised the Dulles terminal control facility, and Dulles urged its controllers to look for primary targets. At 9:32, they found one. Several of the Dulles controllers "observed a primary radar target tracking eastbound at a high rate of speed" and notified Reagan National Airport. FAA personnel at both Reagan National and Dulles airports notified the Secret Service. <sep>What caused concerns over the safety of other aircraft began to mount?<sep>No contact

A: No

Q: Spain's Golden Age: Under Ferdinand and Isabella, Spain underwent a dramatic transformation. In 1492 the royal pair presided over the final conquest over the Moors and discovery of the New World, including the great wealth that feat brought to Spain. Spain flourished during a Golden Age, a century of Spanish economic and political supremacy in international affairs, accompanied by marvels of art and literature. Ferdinand and Isabella were consummate Spaniards, committed to the expansion of the crown. By contrast, their grandson, who assumed the throne in 1516, was born in Flanders in 1500, and Charles I could barely express himself in Spanish. The first of the Habsburgs, he packed his retinue with Burgundian and Flemish nobles. Soon after his arrival in Spain, the young man inherited the title of Holy Roman Emperor, as Charles V. The responsibilities of the crown kept him busy away from the royal residences of Toledo, Segovia, Valladolid, and Madrid. While the monarch was away on one of his many business trips, his increasingly dissatisfied subjects protested violently. A revolt of the comuneros, or townsmen, broke out in a number of Spanish cities, including Madrid. The rebels occupied the alcazar, which had by then been converted to a royal palace. The insurrection was quashed and its leaders executed, but the king got the message. He tried thereafter to pay more attention to his Spanish constituency. <sep>Who were the grandparents of the individual that assumed the throne in 1516?<sep>Donnie and marie
