Multiple news outlets are reporting a bizarre incident aboard an American Airlines flight from Dallas to Chicago that left two flight attendants injured and grounded the flight.

According to those reports, it started when a female flight attendant took to the public-address system this morning on Flight 2332 as it was preparing to depart Dallas-Ft. Worth (DFW) for Chicago O’Hare International (ORD).

Some passengers used their Twitter accounts to describe it, saying the flight attendant started ranting about mechanical problems aboard the aircraft and saying the plane was going to crash. According to some of those passengers, the woman had to be physically subdued by fellow flight attendants.

A later report on the incident in the Chicago Tribune includes raw video shot by passengers aboard the flight. You can’t really see anything, but starting at about the 1:44 mark, you can hearthe flight attendant screaming as if she were…well…possessed.

American Airlines, which recently filed for Chapter 11 bankruptcy protection, has been losing hundreds of millions of dollars at an alarming rate and is jousting with employee unions in a bid to cut pensions and lay off thousands of workers.
