9:24 a.m.-9:25 a.m. September 11, 2001: Flight 93 Checks in with Cleveland Air Traffic Control, Mentions No Problems

Having entered the center’s airspace, Flight 93 establishes radio contact with the FAA’s Cleveland Center, a regional air traffic control center that guides long-range, high altitude flights. The pilot reports simply that his flight is experiencing intermittent light choppy air, and does not indicate there being any problems on board, saying, “Good morning Cleveland, United 93 with you at three-five-oh [35,000 feet], intermittent light chop.” The controller, John Werth, is busy with other flights, so does not initially respond. A minute later, Flight 93 radios again, “United 93 checking in three-five-oh.” Werth replies, “United 93, three-five-zero, roger.” [Gregor, 12/21/2001 ; Longman, 2002, pp. 69; 9/11 Commission, 8/26/2004, pp. 37; CBS News, 9/10/2006] Two minutes later, Flight 93 will make its final radio communication before the hijacker takeover occurs (see 9:27 a.m. September 11, 2001).
