The North American Aerospace Defense Command says two F-22 and two CF-18 fighter jets identified two Russian Tu-160 Blackjack strategic bombers that were entering an area patrolled by the Royal Canadian Air Force on Saturday morning. There were no reports of conflict between the Russian and the US and Canadian jets. NORAD says it uses radar, satellites and fighter aircraft to patrol the skies and monitor aircraft entering US or Canadian airspace. “NORAD’s top priority is defending Canada and the United States. Our ability to protect our nations starts with successfully detecting, tracking, and positively identifying aircraft of interest approaching US and Canadian airspace,” General Terrence J. O’Shaughnessy, the NORAD commander, said in a statement.
