Hijacker stopped for speeding two days before attacks
A Maryland police officer stopped one of the September 11 hijackers for speeding just two days before the US terror attacks.
The state force has released a video of the moment filmed by a dashboard-mounted camera in his patrol car.
It didn't capture any images of Ziad S Jarrah, who was one of the hijackers aboard United Airlines Flight 93 which crashed in Pennsylvania.
A police spokesman said the officer was wearing a wireless microphone and the audio track captured the driver giving simple "yes" and "no" answers to the trooper's questions, according to reports.
The state trooper stopped Jarrah for speeding on Interstate 95 shortly after midnight on September 9. In the video, the officer can be seen approaching Jarrah's car, obtaining his driver's licence and registration, and returning to the patrol car for a radio check of the credentials.
Police said the trooper then is seen returning to the driver's car and is heard explaining the citation as he obtains a signature on the ticket.
A month after the hijackings, US authorities discovered a letter written by Jarrah to his girlfriend in Germany and postmarked September 10.
In the letter, which was mistakenly addressed and returned to the US, Jarrah told his girlfriend he had done his duty.
"I have done what I had to do," he wrote. "You should be very proud, it is an honour, and you will see the result, and everyone will be happy."
