At 8:45 a.m., Larry Wansley learns of the hijacking of Flight 11. Wansley is the managing director of corporate security for American Airlines, and is at the company’s headquarters in Fort Worth, Texas. He is informed of the hijacking in an urgent phone call from the airline’s Command Center, located on the floor above its System Operations Control (SOC), about a mile away from headquarters (see (Between 8:40 a.m. and 8:55 a.m.) September 11, 2001). The SOC learned there was some kind of problem with Flight 11 at 8:20 a.m. (see 8:20 a.m. September 11, 2001). Since as early as 8:21, details of Flight 11 attendant Betty Ong’s emergency call have been constantly relayed to Craig Marquis, a manager at the SOC (see 8:21 a.m. September 11, 2001). Yet the 8:45 call is apparently Wansley’s first notification of the hijacking. He calls Danny Defenbaugh, the special agent in charge of the Dallas FBI office. Wansley is himself a former undercover FBI agent, and Defenbaugh is a longtime friend of his. This call is “the first step in the well-researched, secret hijack-response plan all commercial airlines have in place.” As Wansley is relaying information, he hears screaming from an adjacent conference room, as several employees watch the aftermath of the first WTC crash on television. The TV in Defenbaugh’s office has been turned on, but reportedly neither of the two men connects the images of the burning tower with the hijacking they are trying to deal with. As they continue discussing their response plans, television shows the second plane hitting the South Tower. No doubt realizing this is a terrorist attack, Defenbaugh says, “The ball game just changed.” Around this time, Wansley learns that the first plane to hit the WTC was the hijacked American Airlines flight. He will subsequently make a hurried drive to the nearby Command Center, where the FBI will already be setting up its own command post (see Shortly After 8:46 a.m. September 11, 2001).
