What was the real reason the FBI didn't want to release Flight 93's cockpit recordings?

FBI refuses to release cockpit tape from hijacked flight

"The FBI has turned down family requests that it release the cockpit voice recording from an airliner hijacked on Sept. 11 that crashed in a Pennsylvania field, saying the horror captured on the tape would do little to assuage their grief.
"(FBI) Director (Robert) Mueller has personally listened to the recording from the hijacked flight and advised that the FBI will not be releasing the tape at this time," an FBI spokesman said in a letter to U.S. Rep. Ellen Tauscher.
"While we empathize with the grieving families, we do not believe that the horror captured on the cockpit voice recording will console them in any way," the spokesman said.
Tauscher, a California Democrat, had written to the FBI on behalf of Deena Burnett, whose husband Thomas was among those aboard the plane when it was hijacked on Sept. 11.
Unlike three other passenger jets hijacked that day that crashed into the World Trade Center and the Pentagon, United Flight 93 crashed into a field in Pennsylvania, apparently brought down amid a passenger revolt against the hijackers." -Houston Chronicle/Reuters (12/20/01)

Three-minute discrepancy in tape - Cockpit voice recording ends before Flight 93's official time of impact

"THE FINAL three minutes of hijacked United Flight 93 are still a mystery more than a year after it crashed in western Pennsylvania - even to grieving relatives who sought comfort in listening to its cockpit tapes in April.
A Daily News investigation has found a roughly three-minute gap between the time the tape goes silent - according to government-prepared transcripts - and the time that top scientists have pinpointed for the crash.
Several leading seismologists agree that Flight 93 crashed last Sept. 11 at 10:06:05 a.m., give or take a couple of seconds. Family members allowed to hear the cockpit voice recorder in Princeton, N.J., last spring were told it stopped just after 10:03.
The FBI and other agencies refused repeated requests to explain the discrepancy.
Aviation experts said there could be several explanations for the gap.
...President Bush and other top government officials continue to invoke the story - based largely on the cell-phone calls - of fighting between the passengers and the hijackers as a "Let's roll" rallying cry to continue the war against global terrorism.
But the FBI has clamped a tight lid of secrecy on the flight data recorder - which could best show how Flight 93 actually crashed - and on the cockpit voice recorder.
An FBI spokesman, Steven Berry, said the bureau continues to officially list the time of the Flight 93 crash as 10:03 a.m. The NTSB referred all questions to the FBI.
But the relatives of Flight 93 passengers who heard the cockpit tape April 18 at a Princeton hotel said government officials laid out a timetable for the crash in a briefing and in a transcript that accompanied the recording. Relatives later reported they heard sounds of an on-board struggle beginning at 9:58 a.m., but there was a final "rushing sound" at 10:03, and the tape fell silent.
"There is no sound of the impact," said Kenneth Nacke, whose brother, Lou Nacke Jr., is one of the passengers believed to have fought with the hijackers. Nacke confirmed that the government said the tape ended at 10:03 a.m.
"The seismic signals are consistent with impact at 10:06:05," plus or minus two seconds, said Terry Wallace, who heads the Southern Arizona Seismic Observatory and is considered the leading expert on the seismology of man-made events. "I don't know where the 10:03 time comes from."
None of the family members interviewed for this story recalls any explanation of a discrepancy between the times on the tape recording and the actual crash at 10:06.
Investigators typically nail down the correct times very early in a probe, experts said. Todd Curtis, who runs the Web site, said the three-minute gap "does not make sense."
But the three-minute gap is certain to fuel ongoing debates on the Internet over how Flight 93 really crashed, and whether the plane could have been shot down by military jet fighters that were sent aloft as the Sept. 11 hijackings unfolded. The government insists there was no shoot down.
Numerous witnesses in the Shanksville area have told the Daily News and other publications since last September that a mysterious, low-flying unmarked white jet, military in nature, circled the area at the time of the crash. The FBI has claimed this was a business jet that had been asked by air-traffic controllers to inspect the Flight 93 crater.
The debate has also been driven by the wide debris field from Flight 93 - including papers found eight miles away - and by conflicting accounts over whether a 911 caller reported an explosion and white smoke on board.
Grose, the former NTSB member, said he doubts the entire story of Flight 93 will ever be told.
"I don't think so," he said. "It's like David Crockett at the Alamo. We need heroes." -Philadelphia Daily News (9/16/02) [Reprinted at:]
