The alleged hijackers and their doubles :
Here a brief presentation of the surprising contradictions of several alleged hijackers concerning their language skills. Besides their location and their physical appearance this parameter seems important in order to conclude if there have been doubles or not. (I base this on the assumption that it is difficult to fake a fluent English without accent if one originally had a strong accent and could barely speak English).
Atta spoke German almost without any accent.
For his English:
Brad Warrick who rented Atta a car and met him twice said:
“He had very little accent and acted like he was a businessman.
“He seemed to be a businessman,” Mr. Warrick said. “His driver’s license and insurance matched up to a Florida address, he had a credit card, he spoke very good English, and he carried a briefcase. He seemed pretty friendly.”

In general his English is described as good or quite good.
Marian Smith who rented Atta a Piper in middle of August
Whitener at Gwinnett County Airport who once talked to him.
But on the other hand we have also an Atta in Shuckums on September 7 who is clearly described as having a “thick accent”.
Can he be the same?
We have the change of Atta in North Port seen by his landlords.
At first Amanda Keller has to translate for him (I assume he must have talked in French! As she didn’t understand German and certainly not Arab. Therefore a real language genius!) and he “spoke limited English”. Then he comes back from a party and spoke “good English”!
Besides Shuckums we have another case where Atta is supposed to have spoken with a heavy accent: The voice talking to the passengers on AA 11.
It’s usually described “as heavily accented? or “thickly accented”.
Could this be Atta?
Mohand Al Shehhi:
A real language genius.
All agree that he spoke German almost fluently. This is already an achievement as he only came to Germany as an adult.
But he also spoke ? good English, with either no or only a slight accent, said Diane Surma.”
Dekkers and Voss judge that his English (like Att!) “not totally good but not bad.”
