At Boston’s Logan Airport, from which Flight 11 and Flight 175 took off, directors learn that a plane thought to be from there has hit the World Trade Center, and another from there is missing. John Duval, the airport’s deputy director of operations, is at his desk in the executive aviation office, when his son calls and informs him of the first plane hitting the WTC. A duty manager then calls, saying he has been on the phone with the FAA control tower at the airport. The manager tells Duval he has been informed that, as well as the plane that hit the WTC, “Another one is missing,” and, “They think the two planes came from here.” Duval immediately calls Ed Freni, who is Logan’s director of aviation operations. Duval passes on the news of the WTC crash and the other information from his duty manager. The two men arrange to meet in five minutes time at the Massachusetts Port Authority (Massport) aviation office on the 18th floor of the FAA control tower at the airport. [Murphy, 2006, pp. 30-33]
