United States Air Force and Canadian fighter aircraft were scrambled to escort two Russian bombers traveling near the North American coast.
The North American Aerospace Defense Command reported that two F-22 and two CF-18 fighters identified two Russian Tu-160 Blackjack strategic bombers that were entering an area patrolled by the Royal Canadian Air Force on Saturday morning.
The United States uses radar, satellites and fighters to patrol the skies and monitor arrivals in US or Canadian airspace.
Commanding general Terrence O'Shaughnessy of NORAD noted: "Our ability to protect our nations starts with detecting, tracking, and positively identifying aircraft of interest approaching US and Canadian airspace."
