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

(CNN) -- Deposed Honduran President Jose Manuel Zelaya will not be reinstated as head of state, an overwhelming majority of the Honduran congress voted Wednesday. In an hours-long process, 111 lawmakers voted in favor of a motion not to return Zelaya to office. A majority of 65 votes in the 128-member body was required to reject his reinstatement. Zelaya was removed from office in a military-led coup on June 28 and replaced by congressional leader Roberto Micheletti. On Wednesday, lawmakers voted one by one and addressed the chamber as they cast their vote, making for a slow process. The vote was a key part of a U.S.-brokered pact that representatives for Zelaya and Micheletti signed October 29, giving Congress the power to decide Zelaya's fate. The United States expressed disappointment Thursday over the latest rebuff to its diplomatic efforts to end the political crisis in Honduras. U.S. Assistant Secretary of State for Western Hemisphere Affairs Arturo Valenzuela continued to call on the Honduran government to allow Zelaya's return and to create a unity government in the interim period before the new president takes office next month. "We are disappointed by this decision since the United States had hoped the [Honduran] Congress would have approved his return," Valenzuela said in a conference call with journalists in Washington. "Our policy since June 28 has been consistently principled. It has condemned the coup d'etat and continued to accept President Zelaya as the democratically elected and legitimate leader of Honduras throughout this political crisis." The United States continues to call for Honduras to engage in national reconciliation and creation of a truth commission to investigate the crisis, in addition to the unity government. "The absence of democratic, constitutional order is the unacceptable status quo," a senior U.S. administration official said on the conference call, remaining anonymous under the ground rules of the call and because of the sensitivity of the situation. "The election is a step toward a day where Honduras will have an electorally legitimate government in place." <sep>Out of the 128-member body, how many lawmakers voted not to return Zelaya to office?<sep>65

A flood occurs when a river overflows its banks. This might happen because of heavy rains. Floodplains In very flat regions, flood water may spread out on the surface of the land. It then slows down and drops its sediment. If a river floods often, a floodplain develops. A floodplain is an area where a thick layer of rich soil is left behind as the floodwater recedes. Thats why floodplains are usually good places for growing plants. They are very flat areas and they have very rich soils. The Nile River valley is a great example of a floodplain. Each year, the Nile River rises over its banks. This floodwater carries a lot of sediment. This sediment has been eroded off areas of land from upstream. This sediment is dropped as the water slows down after spreading across the land. What is left behind is a very rich soil. Thats why crops can be raised in the middle of a sandy desert. Natural Levees A flooding river often forms natural levees along its banks. A levee is a raised strip of sediments deposited close to the waters edge. <sep>What might cause a river to overflow its banks?<sep>Heavy rainfall

Yes
