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 was ordered at the Command Center at 9:25?<sep>Grounding
Yes

(CNN) -- The photographer who took images of former Pakistani Prime Minister Benazir Bhutto moments before her assassination Thursday told CNN he was "surprised" to see her rise through the sunroof of her vehicle to wave to supporters after delivering her speech. Getty Images photographer John Moore captured Benazir Bhutto waving, moments before he heard gunshots. "I ran up, got as close as I got, made a few pictures of her waving to the crowd," Getty Images senior staff photographer John Moore told CNN's online streaming news service, CNN.com Live, in a phone interview Thursday from Islamabad, Pakistan. "And then suddenly, there were a few gunshots that rang out, and she went down, she went down through the sunroof," he said. "And just at that moment I raised my camera up and the blast happened. ... And then, of course, there was chaos." Watch Moore describe Bhutto's final moments » Moore said he was about 20 yards away from Bhutto's vehicle when he took his photographs. Bhutto was rushed to Rawalpindi General Hospital, where she was pronounced dead. Moore said he had been following Bhutto's story since her return to Pakistan in October. He was present October 19 when a terror attack targeting her motorcade in Karachi killed 136 people. In the aftermath of that attack, "The rallies had been very small," because of high security, Moore said. However, the Rawalpindi rally was announced beforehand, he observed. "Whoever planned this attack -- they had time on their hands to plan everything properly, and you saw the results today," he said. Between 5,000 and 8,000 were at the Rawalpindi rally, which was held at a parkground, he said. "We [the news media] all expected it to be filled ... but there were less people there than most of us expected to see," he said. "When I talked with a number of people, they said that people were just afraid to come out, for the simple reason that they all remembered what happened in Karachi." Moore said he himself expected there could be another attack following the Karachi massacre. He said he stayed away from gates at the Rawalpindi parkground, where police were searching people, because he suspected that's where a bomb would go off. <sep>What gave the assassins time to properly plan their attack?<sep>The time between the parade and the rally
No

The 1933 double eagle, a $20 gold piece with a mysterious history that involves a president, a king and a Secret Service sting operation, was auctioned Tuesday last night for a record price for a coin, $7.59 million, nearly double the previous record. The anonymous buyer, believed to be an individual collector who lives in the United States, made the winning bid in a fiercely contested nine-minute auction at Sotheby's in Manhattan. Eight bidders were joined by 500 coin collectors and dealers in an auction house audience seemingly devoid of celebrity bidders, while an additional 534 observers followed the bidding on eBay. As auction houses prepare for their fall seasons in an uncertain economy, the sale price "suggests that the marketplace for important items is enormously strong," said David Redden, a vice chairman at Sotheby's, who was the auctioneer. "This is an astonishing new record for a coin," he said. In an unprecedented move, the auction proceeds were split by the U.S. Mint and a London coin dealer, Stephen Fenton, who had won that right in court after having been arrested by Secret Service agents for trying to sell the coin in the Waldorf-Astoria Hotel in Manhattan in 1996. Henrietta Holsman Fore, the director of the U.S. Mint, who witnessed the sale, said, "The monies we receive will go toward helping to pay down the debt and to fight the war on terrorism." Fenton commented that the double eagle had been on "a long historic journey, with a very satisfying ending." He added, "I am thrilled with the price." The previous numismatic record holder was an 1804 U.S. silver dollar, which sold for $4.14 million in 1999. Sotheby's partner in the one-lot auction was Stack's Rare Coins, with which it shared the customary 15 percent commission. "I have never seen as much interest in the sale of any coin in my 30 years in the business," said Lawrence R. Stack, the company's managing director. "This is the Mona Lisa of coins," said Beth Deisher, editor of Coin World, the largest weekly coin publication in the United States, with a circulation of 85,000. "It is unique. Forbidden fruit." Collectors' Web sites have surged with speculation about the sale price, and enthusiasts even organized betting pools. <sep>Who stated, "This is an astonishing new record for a coin?"<sep>Fenton
