MIAMI (AP) - Authorities say a false hijacking alarm forced fighter jets to escort an American Airlines flight onto the tarmac at Miami International Airport.
Airlines spokesman Tim Smith says flight 535 was arriving from San Juan, Puerto Rico, Monday when the false alarm was reported.
He says the plane's transponder frequency was inadvertently switched
to a frequency that indicates a hijacking. The transponder is found in the cockpit.
Fighter jets from Homestead Air Force Base escorted the plane onto a remote area of the tarmac at 1:42 p.m.
Police secured the plane. No one was injured.
Smith says this was "very unusual."
The plane was carrying 148 passengers and six crew members.
Airport and police would not release further information about the false alarm.
