Chicago-bound Flight 2332 had left the gate at Dallas/Fort Worth International Airport when the flight attendant got on the intercom and began a tirade that alarmed passengers, The Dallas Morning News reported.
Passengers managed to subdue the attendant, but not before two other crew members were injured in the scuffle, the newspaper said.
The flight attendant "came on the PA system ranting about AA bankruptcy and then telling them the plane was going to crash," the sister of one woman on the plane told the News.
"She was addressing the captain, telling him not to take off, that it would not be her responsibility when the plane crashes and that it was going to crash. Then she was tackled by first-class passengers, who threw her against the wall."
Another passenger sent an e-mail to a friend saying, "The flight attendant went crazy, screaming about 9/11 and crashing. Six men held her down."
American Airlines said in a statement: "This morning Flight 2332 had left the gate at DFW bound for Chicago, when an incident occurred involving some of the cabin crew. The aircraft returned to the gate, where it was met by Department of Public Safety officers. Two flight attendants were taken to local hospitals for treatment. …
"We will ensure that the affected flight attendants receive proper care, and we commend our other crew members for their assistance in quickly getting the aircraft back to the gate so that customers could be re-accommodated. Our customers were not in danger at any time."
The cabin crew was replaced and the flight departed for Chicago at 9:46 a.m., about 80 minutes late, the airline said.
