A small jet plane—ExecuJet 956—tracks Flight 93 for what is described as “a substantial period of time” before it crashes, and picks up some of the radio transmissions from it, as both planes are operating on the same frequency. [Government’s motion for protective order regarding cockpit voice recorder pursuant to 49 USC 1154. United States v. Zacarias Moussaoui, 8/8/2002 ; Washington Post, 8/9/2002] The exact period over which ExecuJet 956 follows Flight 93 is unclear. But as early as 9:31 it calls the FAA’s Cleveland Center and, referring to Flight 93, reports: “[W]e’re just answering your call. We did hear that, uh, yelling too.” [9/11 Commission, 7/24/2004, pp. 461] At 9:40, after being asked, “did you understand that transmission [from Flight 93]?” ExecuJet 956 tells Cleveland Center: “Affirmative. He said that there was a bomb on board.” [Associated Press, 4/12/2006] Cleveland Center then asks the ExecuJet pilot if he can change course and try to spot Flight 93. He sees it, loses it, and then sees it again. He then has to make an evasive turn, as Flight 93 is heading directly for him. [Longman, 2002, pp. 104] ExecuJet 956 is one of a fleet of small jets available for hire from a company based in Woodbridge, New Jersey called NetJets, which sells shares in private business aircraft. [Associated Press, 8/8/2002; Washington Post, 8/9/2002] NetJets’ owner is the multi-billionaire Warren Buffet. [Knight Ridder, 11/6/2001; Observer, 1/12/2003] Another small business jet is reportedly within 20 miles of Flight 93 when it crashes, but this is apparently a different one, belonging to a North Carolina clothing firm (see 10:07 a.m. September 11, 2001).
