Passengers and flight attendants told law-enforcement officials the imams switched from their assigned seats to a pattern associated with the September 11 terrorist attacks and also found in probes of U.S. security since the attacks --
two in the front row first-class, two in the middle of the plane on the exit aisle and two in the rear of the cabin.
"That would alarm me," said a federal air marshal who asked to remain anonymous. "They now control all of the entry and exit routes to the plane."

According to witnesses, police reports and aviation security officials, the imams displayed other suspicious behavior.
Three of the men asked for seat-belt extenders,
although two flight attendants told police the men were not oversized.
One flight attendant told police she "found this unsettling, as crew knew about the six [passengers] on board and where they were sitting." Rather than attach the extensions, the men placed the straps and buckles on the cabin floor, the flight attendant said.

The imams who claimed two first-class seats said their tickets were upgraded. The gate agent told police that when the imams asked to be upgraded, they were told no such seats were available. Nevertheless, the two men were seated in first class when removed.
A flight attendant said one of the men made two trips to the rear of the plane to talk to the imam during boarding, and again when the flight was delayed because of their behavior. Aviation officials, including air marshals and pilots, said these actions alone would not warrant a second look, but the combination is suspicious.
"That's like shouting 'fire' in a crowded theater. You just can't do that anymore," said Robert MacLean, a former air marshal.
"They should have been denied boarding and been investigated," Mr. MacLean said. "It looks like they are trying to create public sympathy or maybe setting someone up for a lawsuit."
The pilot with another airline who talked to The Washington Times on condition of anonymity, said he would have made the same call as the US Airways pilot.
"If any group of passengers is commingling in the terminal and didn't sit in their assigned seats or with each other, I would stop everything and investigate until they could provide me with a reason they did not sit in their assigned seats."

Now of course these are just eyewitness accounts from people that were there.
