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

Ex Output:
No

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>Why were the Spanish people unhappy with Ferdinand and Isabella's grandson, Charles V?<sep>Charles V was born in Flanders in 1500 and was barely able to express himself in Spanish and when he assumed the throne in 1516 packed his retinue with Burgundian and Flemish nobles
