Problem: 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.

Question: "How long was there between the flight failing to heed instructions and the transponder being turned off?"

Answer: "1 minute"
Answer: no

Problem: In remarks during a ribbon-cutting ceremony here on Wednesday, Gov. George E. Pataki said he expected the facility to generate thousands more jobs in the Hudson Valley area for contractors and suppliers catering to the factory. He praised IBM for being "a critical partner in our economic development efforts" in New York state. In a brief speech, Samuel J. Palmisano, IBM's chief executive, emphasized that it was important to make long-term investments despite the current slump in the technology business. "To play to win in technology, you innovate and you lead," he said. But manufacturing technology products is a costly and cyclical business. In June, IBM announced that it was taking a charge of more than $2 billion against earnings. The largest single reasons for the charge were the cost of getting out of the business of manufacturing hard disks for storage, which it sold to Hitachi, and closing down some of its older semiconductor operations. But Kelly said the demand for advanced chips, like those produced at IBM's facility in Burlington, Vt., is strong. "I need more capacity in that end of the market," he said, "and this is factory is critical to meeting that growing demand." If IBM has miscalculated the demand, it will suffer badly as both the high operating costs and depreciation on the huge capital investment for the East Fishkill factory drag down earnings. But industry analysts said the plant should be insulated from a falloff in one or a few segments of the semiconductor market.

Question: "Who asked for more capacity in that end of the market?"

Answer: "Palmisano"
Answer: no

Problem: Earths magnetic field helps protect Earth and its organisms. It protects us from harmful particles given off by the sun. Most of the particles are attracted to the north and south magnetic poles. This is where Earths magnetic field is strongest. This is also where relatively few organisms live. Another benefit of Earths magnetic field is its use for navigation. People use compasses to detect Earths magnetic north pole. Knowing this helps them tell direction. Many animals have natural 'compasses' that work just as well. Birds like the garden warbler in Figure 1.36 use Earths magnetic field. They use it to guide their annual migrations. Recent research suggests that warblers and other migrating birds have structures in their eyes. These structures let them see Earths magnetic field as a visual pattern.

Question: "What is unique about the north and south magnetic poles?"

Answer: "It holds the gravitational pull of the planet"
Answer:
no
