The first breakthrough came for investigators within hours of the attack when a motorist contacted them to say he had been involved in a squabble with some Arabs in the car park of Boston's Logan Airport, from where two of the planes were hijacked.
Police found a car contained flight manuals in Arabic, instructional videotapes on how to fly a large plane, a copy of the Koran, and a fuel calculator guide.
It was rented by a man called Mohamed Atta, a 33-year-old United Arab Emirates passport holder, three days ago in Boca Raton, Florida. He had given an address in Florida. He was named on the passenger list for United flight 175 from Boston, which was the second plane to hit the World Trade Centre.
Source of claim:
I ask because I always remembered that one of the early reports back at the time was an odd claim about finding a copy of the Koran, and a fuel calculator and a guide to flying a plane. Though when I first heard the story the version was one which claimed that the items had been found in a misdirected item of luggage.
While some might take the newspaper here alone as a credible source I'm asking about this because this appears to barely be mentioned anywhere else.
Googling ["fuel calculator" "Mohamed Atta"] appears to yield only 6 google hits and most are conspiracy sites.
Given how much ink has been spilled about the event it seems odd that this isn't mentioned elsewhere.
