The Russian aircraft were"intercepted and
monitored by the F-22s until the bombers left the Adiz along the Aleutian Island chain heading west", and never entered USA airspace, according to the statement.
According to the statement issued by the media, the detection and
monitoring of the aircraft in the air defense identification zone(Adiz) of the United States
or Canada shows how the NORAD adheres to its airspace warning and airspace control mission.
