There's still not a lot of official word on the Air France/Paris-L.A. connection: Nothing on the Department of Homeland Security web site, nothing on the TSA web site, nothing on the State Department web site, nothing on P.R. Newswire.

AFP reports that, from what they hear, the fear wasn't al Qaeda infilitrated the airline:

A US Homeland Security Department official said that as a result of a "credible threat," US authorities had given France the names of suspicious passengers on the manifests of three Los Angeles-bound flights.

"The threat was coming from passengers, not from the pilots," the official, who declined to be named, told AFP.

France's interior ministry said some of the passengers who were due to take Wednesday's flight had been questioned but nothing was found to suggest any terrorist link. No passengers were arrested.

Still, no named U.S. official is putting their face to this story. Here's the additional thought:

On Sept. 11, 2001, al Qaeda hijacked four planes from multiple airlines. If they used that as a template for any new attack, would there be other airlines involved?

No one is saying, for now.
