[EX Q]: 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>At which times did all this take place<sep>8:45

[EX Q]: (OPRAH.com) -- Chris Rock is an Emmy-winning comedian, devoted husband and loving father --but it's time to get to know a new side of this funnyman. Meet Chris Rock, hair expert. It's a detour he took after an innocent carpool ride left Rock with an idea he just couldn't shake. "I was with my daughter one day, and we're in the car and she's with one of her friends in the back seat, a little white friend," he says. "She was just kind of raving about her friend's hair a little too much for my comfort [saying]: 'You've got great hair. Oh, your hair's so good.'" Not wanting to make her comments a big deal, Rock says he tried to play his them off. "[I said]: "Oh, baby, your hair's beautiful. Come on,'" he says. "If I would have really reacted, then she would have a complex about her hair." Still, Rock couldn't let it go. "It sparked something in me," he says. Oprah.com: Oprah's hair throughout the years! What Rock discovered is a $9 billion industry that affects the daily activities, wallets, self-esteem -- and even the sex lives -- of black women. Because women spend so much time and money on their hair, Rock says men are forced to adopt a hands-off policy. "You cannot touch a black woman's hair. You are conditioned not to even go there," he says. "When I was a dating guy, I dated women from different races. Anytime I was with an Asian or a Puerto Rican girl or a white girl, my hands would constantly be in their hair. <sep>What did Chris Rock's carpool ride help him discover?<sep>Hair
