[Source: Jim Varhegyi]The United Airlines Operations Center at JFK Airport in New York sends a text message to LeRoy Homer, the co-pilot of Flight 93, but receives no response from him. [9/11 Commission, 8/26/2004, pp. 37] At 9:10, Melodie Homer, the wife of LeRoy Homer, contacts the operations center after seeing the second plane hitting the World Trade Center on television. Knowing her husband is flying, she requests that a message be sent to him, stating, “Your wife just wants to make sure you’re okay.” [Pittsburgh Channel, 9/19/2001; Longman, 2002, pp. 78; New York Observer, 2/15/2004; Discovery Channel, 2005] Melodie is told, “If you want to hang on, we’ll get a message back in a couple of minutes.” According to journalist and author Jere Longman, after no response is received, a second text message is sent. Although Melodie Homer’s message is later determined to have been received by the flight, there is still no reply. [Longman, 2002, pp. 81-82] However, the 9/11 Commission will only describe one message—not two—being sent to Homer, which it says happens at 9:22. [9/11 Commission, 7/24/2004, pp. 456; 9/11 Commission, 8/26/2004, pp. 37] The hijacking of Flight 93 is believed to take place at 9:28 (see (9:28 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 11] A text message sent by an airline dispatcher to Flight 93’s pilot Jason Dahl shortly before the hijacking will receive a response from him three minutes later (see 9:23 a.m.-9:26 a.m. September 11, 2001).

Shortly after he learns a second plane has hit the World Trade Center, United Airlines flight dispatcher Ed Ballinger takes the initiative to begin sending a warning message to the flights he is monitoring, including Flight 93 and Flight 175 (although this aircraft has already crashed). [9/11 Commission, 7/24/2004, pp. 11; 9/11 Commission, 8/26/2004, pp. 26 and 37] Ballinger is responsible for monitoring United’s aircraft flying from the East Coast to the West Coast. He has 16 such flights he is in charge of. [Chicago Daily Herald, 4/14/2004] He sends out a text message to his airborne flights: “Beware any cockpit intrusion… Two aircraft in NY hit [World] Trade Center builds.” [9/11 Commission, 7/24/2004, pp. 11; 9/11 Commission, 8/26/2004, pp. 26] Although United Airlines has suspected Flight 175 as being hijacked since around 9:00 a.m. (see Shortly Before 9:00 a.m. September 11, 2001), Ballinger is still responsible for multiple flights. (In contrast to United, American Airlines has a policy that flight dispatchers should only manage the hijacked flight, and be relieved of responsibility for their other flights.) [9/11 Commission, 7/24/2004, pp. 455-456] Ballinger’s warning is therefore sent out to his aircraft in groups, and will not be sent to Flight 93 until 9:23 a.m. (see 9:23 a.m.-9:26 a.m. September 11, 2001). Unaware that it was the second plane that hit the WTC, Ballinger will also send the message to Flight 175 (see 9:23 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 26 and 37] Ballinger begins sending out these warnings two minutes before United Airlines instructs its dispatchers to warn their flights to secure their cockpit doors (see 9:21 a.m. September 11, 2001). [9/11 Commission, 1/27/2004; 9/11 Commission, 7/24/2004, pp. 455] According to the 9/11 Commission, his text message represents “the first occasion on 9/11 when either American or United sent out such a warning to their airborne aircraft.” [9/11 Commission, 8/26/2004, pp. 37] Ballinger will later recall: “As soon as I had a grasp of what was going on… I sent [the warning] out immediately. It was before [Transportation Secretary Norman] Mineta, and even before the airlines told us to alert the crews.” [Chicago Daily Herald, 4/14/2004]

United Airlines issues a companywide order for its flight dispatchers to warn their flights to secure their cockpit doors. [9/11 Commission, 1/27/2004; 9/11 Commission, 7/24/2004, pp. 455] The airline’s air traffic control coordinator sends a message to all of the airline’s dispatchers, telling them: “There may be addnl [additional] hijackings in progress. You may want to advise your flts [flights] to stay on alert and shut down all cockpit access inflt [in flight]. Sandy per Mgmt.” United Airlines dispatchers began notifying their aircraft that planes had crashed into the World Trade Center at 9:03 (see 9:03 a.m. and After September 11, 2001). However, with the exception of one dispatcher (see 9:19 a.m. September 11, 2001), the airline has so far not sent any warnings to its aircraft. [9/11 Commission, 8/26/2004, pp. 36-37] United Airlines did not initially realize the second plane to hit the WTC was one of its own (see Between 9:10 a.m. and 9:20 a.m. September 11, 2001), and it is not until 9:22 that it notifies its dispatchers that UAL Flight 175 has been involved in “an accident” in New York (see 9:22 a.m. September 11, 2001).

Ed Ballinger, the United Airlines flight dispatcher monitoring Flight 93, sends a warning message to this flight, telling the pilots to beware of any cockpit intrusion. [9/11 Commission, 7/24/2004, pp. 11] At 9:21, United Airlines instructed its dispatchers to warn their flights to secure their cockpit doors (see 9:21 a.m. September 11, 2001), but Ballinger had already taken the initiative two minutes earlier to begin warning the 16 flights he is monitoring (see 9:19 a.m. September 11, 2001). His text message reads: “Beware any cockpit intrusion… Two aircraft in NY hit [World] Trade Center builds.” Because this message is sent out to Ballinger’s 16 aircraft in groups, it is not until 9:23 a.m. that it is transmitted to Flight 93. [9/11 Commission, 1/27/2004; 9/11 Commission, 8/26/2004, pp. 26 and 37] The warning is received in the plane’s cockpit one minute later. [9/11 Commission, 7/24/2004, pp. 11] Then, at 9:26, Flight 93 pilot Jason Dahl responds with the text message, “Ed confirm latest mssg plz [message please]—Jason.” Apart from a routine radio contact with the FAA’s Cleveland Center a minute later (see 9:27 a.m. September 11, 2001), this is the last normal communication made from Flight 93’s cockpit before the hijacking occurs. [9/11 Commission, 8/26/2004, pp. 38] Ballinger will later complain: “One of the things that upset me was that they knew 45 minutes before that American Airlines [Flight 11] had a problem. I put the story together myself [from news accounts]. Perhaps if I had the information sooner, I might have gotten the message to [Flight] 93 to bar the door.” [Chicago Daily Herald, 4/14/2004]

Flight 93 makes its last normal communication with air traffic control before being hijacked, acknowledging a routine radio transmission from the FAA’s Cleveland Center. [9/11 Commission, 7/24/2004, pp. 28] Flight 93 checked in with the Cleveland Center a couple of minutes earlier (see 9:24 a.m.-9:25 a.m. September 11, 2001). At 9:27, the Cleveland controller, John Werth, alerts it to another aircraft 12 miles away and to its right, at 37,000 feet: “United 93, that traffic for you is one o’clock, 12 miles east, bound three-seven-zero.” Seconds later, Flight 93 responds, “Negative contact, we’re looking, United 93.” Less than a minute after this, the hijackers appear to enter Flight 93’s cockpit (see (9:28 a.m.) September 11, 2001).

United Airlines flight dispatcher Ed Ballinger sends two messages to Flight 93, which he is monitoring, warning its pilots (who in fact are no longer in control of the plane) to secure the cockpit. At 9:40, he sends the text message to Flight 93: “High security alert. Secure cockpit. Two airliner hit NY Trade Center. And 1 aircraft in IAD missing. And one in EWR missing… too. UAL 175/93 missing.” A minute later, he again sends this message to Flight 93, but with “UAL 175/93 found” added at the end. [9/11 Commission, 8/26/2004, pp. 43] “IAD” is the code for Washington’s Dulles International Airport, from where Flight 77 took off, while “EWR” is the code for Newark Airport, from where Flight 93 took off, so presumably it is these missing aircraft that Ballinger is referring to. [Federal Aviation Administration, 9/17/2001 pdf file] Ballinger sent previous warning messages to Flight 93 earlier on, telling it to “Beware any cockpit intrusion” at 9:23 (see 9:23 a.m.-9:26 a.m. September 11, 2001), and to “Secure cockpit” at 9:33 (see 9:32 a.m.-9:33 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 37 and 39]
