Flight 175 stops transmitting its transponder signal. It is currently flying near the New Jersey-Pennsylvania border. [Guardian, 10/17/2001; Newsday, 9/10/2002; 9/11 Commission, 6/17/2004] However, the transponder is turned off for only about 30 seconds, and then comes back on as a signal that is not designated for any plane on this day. Then, within the space of a minute, it is changed to another new code. But New York Center air traffic computers do not correlate either of these new transponder codes with Flight 175. Consequently, according to an early FAA report, “the secondary radar return (transponder) indicating aircraft speed, altitude, and flight information began to coast and was no longer associated with the primary radar return.” Therefore, while controllers are able “to track the intruder easily… they couldn’t identify it.” However, Dave Bottiglia, the New York Center air traffic controller responsible for Flight 175, is currently trying to locate the already-crashed Flight 11, and therefore supposedly does not notice the transponder code changes on Flight 175 until 8:51 a.m. (see 8:51 a.m.-8:53 a.m. September 11, 2001). [Federal Aviation Administration, 9/17/2001 pdf file; Washington Post, 9/17/2001; 9/11 Commission, 8/26/2004, pp. 21] According to a “Flight Path Study” by the National Transportation Safety Board, the change of Flight 175’s transponder code is the “first indication of deviation from normal routine.” [National Transportation Safety Board, 2/19/2002 pdf file]

The FAA’s Cleveland Center, which had the last contact with Flight 93 before it crashed, suggests that no distress signal indicating a plane crash has occurred was picked up at the time Flight 93 went down. [Federal Aviation Administration, 9/11/2001; Federal Aviation Administration, 9/11/2001] Flight 93 reportedly crashed in rural Pennsylvania at 10:03 a.m. (see (10:03 a.m.-10:10 a.m.) September 11, 2001). [National Transportation Safety Board, 2/19/2002 pdf file; 9/11 Commission, 7/24/2004, pp. 30; USA Today, 9/11/2008] An air traffic controller at the Cleveland Center now says, apparently over an FAA teleconference, that someone has reported seeing black smoke in the vicinity of Flight 93’s last known position, near Johnstown, Pennsylvania. The controller then says, “We’re trying to see if we can get an ELT check.” [Federal Aviation Administration, 9/11/2001; Federal Aviation Administration, 9/11/2001] An “ELT” is an emergency locator transmitter, a device carried on most general aviation aircraft in the US that is designed to automatically start transmitting a distress signal if a plane should crash, so as to help search and rescue efforts in locating the downed aircraft. [Federal Aviation Administration, 3/23/1990; Federal Aviation Administration, 7/12/2001; Aircraft Owners and Pilots Association, 1/22/2009] The Cleveland Center controller’s information, as an FAA timeline will later state, therefore indicates that “[n]o ELT” signal has been picked up in the area where Flight 93 apparently crashed “at this time.” [Federal Aviation Administration, 9/11/2001] Someone at the FAA’s Command Center in Herndon, Virginia, acknowledges the controller’s communication, responding, “Copy that, Command Center.” [Federal Aviation Administration, 9/11/2001] Whether anyone will subsequently report picking up an ELT signal in the area where Flight 93 apparently crashed is unclear. Major Allan Knox, who works at the Air Force Rescue Coordination Center, which is “the contact for credible” ELT signals, will tell the 9/11 Commission that he “does not recall an ELT detection being brought to his attention” today. [9/11 Commission, 10/1/2003 pdf file; 9/11 Commission, 10/6/2003 pdf file] However, an ELT signal was picked up in the New York area by the pilot of an aircraft minutes before Flight 11 crashed into the North Tower of the World Trade Center (see 8:44 a.m. September 11, 2001) and another ELT signal was picked up in the New York area by the same pilot minutes before Flight 175 crashed into the South Tower (see 8:58 a.m. September 11, 2001).

General Hamid Gul, the former head of the Pakistani Inter-Services Intelligence agency (ISI), gives several interviews in which he says Osama bin Laden is not responsible for 9/11, and that he believes the attacks were perpetrated by the Israeli overseas intelligence service, Mossad, and renegade elements within the US Air Force. [Newsweek, 9/14/2001; Tehelka (.com), 9/14/2001; United Press International, 9/26/2001]
Failure of US Air Defenses - Gul points to the failure of the US Air Force to halt the 9/11 attacks. He tells Newsweek: “F-16s don’t scramble in time, though they had 18 minutes after the first plane hit the World Trade Center.… A flight to Los Angeles turns to Washington and is in the air for 45 minutes, and the world’s most sophisticated air defense doesn’t go into action.” [Newsweek, 9/14/2001] In an interview with United Press International editor at large Arnaud de Borchgrave, he says: “The attacks against the Twin Towers started at 8:45 a.m. and four flights are diverted from their assigned air space and no air traffic controller sounds the alarm. And no Air Force jets scramble until 10 a.m. That also smacks of a small scale Air Force rebellion, a coup against the Pentagon perhaps? Radars are jammed, transponders fail. No IFF—friend or foe identification—challenge.” He adds: “In Pakistan, if there is no response to IFF, jets are instantly scrambled and the aircraft is shot down with no further questions asked. This was clearly an inside job.”
Bin Laden Innocent - Gul says he believes Osama bin Laden would have been incapable of perpetrating such a sophisticated attack. When de Borchgrave asks, “What makes you think Osama wasn’t behind September 11?” Gul responds: “From a cave inside a mountain or a peasant’s hovel? Let’s be serious.… He doesn’t have the means for such a sophisticated operation.” He comments: “Within ten minutes of the second Twin Tower being hit… CNN said Osama bin Laden had done it. That was a planned piece of disinformation by the real perpetrators. It created an instant mindset and put public opinion into a trance, which prevented even intelligent people from thinking for themselves.” [United Press International, 9/26/2001] He tells the Indian news website Tehelka.com that blaming bin Laden and Afghanistan “is a convenient bogey to divert attention.” [Tehelka (.com), 9/14/2001]
Blames Israel - Israelis are Gul’s prime suspects for 9/11. He says: “Mossad and its American associates are the obvious culprits. Who benefits from the crime?” [United Press International, 9/26/2001] He tells Newsweek: “I can’t say for sure who was behind [9/11], but it’s the Israelis who are creating so much misery in the world. The Israelis don’t want to see any power in Washington unless it’s subservient to their interests, and President Bush has not been subservient.” [Newsweek, 9/14/2001] In his interview with Tehelka.com, he adds: “One knows that after the Florida fiasco of the presidential election, there is a big rift between the Jewish lobbies and George Bush and his administration. He has not taken a single Jew in his Cabinet. So [Israeli Prime Minister Ariel] Sharon and company are very upset with George Bush. They [the Jewish lobbies] have been told to indulge in acts of terrorism in the past. Why can’t they do it now?” [Tehelka (.com), 9/14/2001]
Supports Taliban and Opposes US Action against Afghanistan - General Gul was the head of the ISI between 1987 and 1989 (see April 1987). [Daily Telegraph, 9/23/2001] As Newsweek describes, he is “widely considered the architect of the Afghan jihad: the man who, with financial and logistical support from the CIA, engineered the fight of the mujaheddin against the Soviet Union and its proxy government in Kabul in the 1980s. Now, he’s a big fan of the country’s ruling Taliban.” [Newsweek, 9/14/2001] He currently serves as an adviser to Pakistan’s extremist religious political parties, which oppose their government’s decision to support the US in any action against the Taliban. [United Press International, 9/26/2001] Newsweek comments: “If General Gul were anyone else, it would be easy to dismiss him as a crackpot. But here in military-ruled Pakistan, he remains an influential figure, even in semiretirement.” [Newsweek, 9/14/2001]
