HOUSTON -- Security officials grounded an American Airlines flight Wednesday afternoon at one of Houston's airports, authorities said.
Airport officials told News2Houston that American Airlines Flight 1702 was held at one of the runways after being escorted by F-16 fighters.
The flight with 50 passengers on board departed Houston at 12:28 p.m. but was returned back to the airport at 1:08 p.m. and then was later docked at the airport terminal.
Houston Airport System spokesman Ernie DeSoto said that the plane was surrounded by security.
U.S. air marshals were also aboard the Dallas-bound flight, DeSoto said.
DeSoto said that initial reports that the incident is an attempted hijacking are false.
Sources said that someone aboard the plane had noticed that one or two passengers were carrying what appeared to be a razor or knife.
Soon after, air marshals took control of the plane after some type of disturbance occurred on the flight and took two men into custody for questioning, sources said.
American Airlines officials said that the captain returned the plane to the airport due to a potential security breach.
No injuries were reported. The airplane is a Fokker F-100, which is a luxury jet with the capacity to carry 97 passengers.
The jet is the smallest aircraft in the American Airlines fleet.
The 98,000-pound aircraft has a range of 1,100 miles and can cruise at 500 mph at altitudes of up to 35,000 feet.
The F-100 has been in service with American since 1991.
