January 07, 2010 WASHINGTON - TWO F-15 fighter jets intercepted an airliner bound for Hawaii on Wednesday and escorted it back to Portland, Oregon after a passenger caused a 'disturbance,' the North American Aerospace Defense Command said.
The Hawaiian Air plane was intercepted at about 1pm local time (2100 GMT, 5am Singapore time) after taking off from Portland, Norad said in a statement.
'Shortly after take-off, a passenger caused a disturbance on the plane and the pilot decided to return the aircraft to Portland,' it said.
The fighter aircraft led the plane back to Portland airport at about 1.15pm and law enforcement officers were investigating the incident, according to the statement, which offered no other details.
Norad, a joint US-Canada mission, scrambles fighter jets to respond to possible terrorist threats from the air, after the attacks of Sept 11, 2001 involving hijacked airliners.
Based in the central US state of Colorado, Norad was created during the Cold War in 1958 to protect North America against air attacks.
