North American Aerospace Defense Command officials are monitoring the situation in London following several early morning explosions there that appear to be an act of terrorism.
Within moments of the explosions, senior NORAD officials reviewed operational plans, procedures and alert posture levels to maintain full situational awareness.
"NORAD alert levels remain high and we will take appropriate steps to adjust our alert posture as necessary," said Michael Perini, NORAD Director of Public Affairs. "Our irregular air patrols are continuing as planned."
The safety and security of North American airspace remains NORAD's prime mission. The command retains a robust air defense posture to maintain air sovereignty over the continental U.S., Alaska and Canada. Since Sept. 11, 2001, NORAD aircraft have flown more than 40,000 sorties as part of Operation Noble Eagle.
