Flight 77 Cockpit Door Never Opened During 9/11 “Hijack"
Pilots for 9/11 Truth has reported that the data stream from the flight data recorder (FDR) for American Airlines flight 77, which allegedly struck the Pentagon on 9/11, shows that the cockpit door never opened during the entire 90 minute flight.
The data was provided by the National Transportation Safety Board (NTSB), which has refused to comment.
The FDR is one of two “black boxes” in every commercial airliner, which are used after accidents to help determine the cause of a crash.
One black box records flight data, the other records voice data (everything said in the cockpit during the flight).
With those two sets of data, NTSB investigators can usually piece together the events that led to a crash.
The status of the door to the cockpit is checked every four seconds throughout a flight and relayed as a simple 0 or 1, where 0=closed and 1=open, with approximately 1,300 door status checks performed during AA77’s 90 minute flight.
Every one of those door status checks shows as a 0, indicating that the door to the cockpit never opened during the entire flight.
Accident investigators monitor the cockpit door with the FDR because it may yield clues to pilot error in a crash.
The FDR begins recording once the pilots are in their seats and readying for takeoff, and the plane cannot take off unless the FDR is working.
The official story about flight 77 is that five Muslim terrorists brandishing box cutters forced their way into the cockpit and herded two pilots, four flight attendants and all the passengers to the back of the plane.
This story came into being via Ted Olson, US Solicitor General, who told CNN — that he received two phone calls from his wife Barbara Olson, a passenger on the doomed flight.
Ted Olson’s story changed several times.
Sometimes he claimed that the calls from his wife were made from seat back phones, other times that she used her cell phone.
According to American Airlines customer service, the American Airlines maintenance manual for that aircraft, and American Airlines Captain Ralph Kolstad, seatback phones on 757s had been deactivated prior to 9/11/01.
(They were later removed entirely, as they never worked well.)
Barbara Olson couldn’t have used a cell phone either: numerous 9/11 researchers, most notably David Ray Griffin, have pointed out that cell phones did not work on airplanes on 9/11.
