(CNN) -- Japan's prime minister conceded defeat in parliamentary elections Sunday, signaling the return to power of the Liberal Democratic Party and ending the brief rule of the disappointing upstart Democratic Party of Japan. Prime Minister Yoshihiko Noda pledged to step down as party president after exit polls showed a smashing loss in lower house voting. The party, once seen as a breath of fresh air in Japanese politics, came to be regarded as increasingly ineffective. "We got a regrettable result," Noda said. "The result is everything in the politics. The biggest responsibility lies on me. I will quit as the partly leader of DPJ." The move clears the way for the return to power of former Prime Minister Shinzo Abe, the current leader of the conservative-leaning Liberal Democratic Party, or LDP. "The Japanese people will be keenly looking whether the LDP can meet with their expectations," Abe said in interviews after the polling. The LDP ruled the country almost continuously since its establishment in 1955 until it was forced from power three years ago by the DPJ. Public broadcaster NHK said the LDP and its coalition partner, the new Komei party, gained at least 302 seats in the 480-seat lower house. CNN's main affiliate, TV Asahi, reports the LDP/Komei coalition gained at least 312 seats. The official count is expected to be released Monday. The LDP is inheriting a struggling economy, regional tensions and questions over Japan's role in Asia. "The economy is at the bottom. It's our first mission to turn it around," Abe said. <sep>As the current prime minister quits as the party leader who can return to power?<sep>Prime Minister Shinzo Abe

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
No

Let me begin again. I like life on the resort worlds -- always have and, after the upcoming mindwipe, always will. Last year, I rented a small house on Vega IV, a sea world, all islands and reefs and archipelagos, turquoise waters and aquamarine skies, sunrises like symphonies and sunsets like stars gone supernova. There's only one city: called Nuevo Acapulco in La Enciclopedia del Empirio de la Humanidad, it's N'apulco to the locals. The N'apulcans are mostly emigrants from Polaris II; the only difference between them and their Carribbean ancestors is that the ancestors fleeced NorAm tourists. Now the N'apulcans profit from their Hispanic siblings. I don't mean to sound cynical. I suppose I wish to show that I'm still capable of a certain authorial distance, a semblance of dispassionate observation. The following events may indicate otherwise. In fine tourist tradition, most homes on Vega IV are named. Mine was The Sleeping Flamingo, and its outer walls were coral pink. Were they mood-sensitive, they would have changed as I first viewed them. The rental agent, an attractive N'apulcan named Tasha Cortez, was not mood-sensitive either. She said, "It's beautiful, isn't it, Senor Flynn?" My instinct was to gesture curtly with a cupped hand that she lift the wind boat and take me elsewhere. But she was young and attractive (as I have said and may say again) and eager and so happy to be assisting the infamous Bernardo Flynn that I merely raised an eyebrow in mild scepticism. And then, because a playwright cannot resist a promising line, I said, "Your Sleeping Flamingo should be put to sleep." <sep>Who rented a small house on Vega IV?<sep>The narrator
