The military will conduct air interceptions of mock hostile aircraft over Phoenix this week.
The Western Air Defense Sector exercises are set for Thursday between 10 a.m. and 1 p.m. They'll involve F-16 fighters, military versions of the Lear Jet 35A business jet and Civil Air Patrol planes. People in the Phoenix area may see the aircraft.
The air defense exercise code-named "Felix Hawk" is designed to test the military's intercept and identification procedures for dealing with a variety of potentially hostile aircraft.
Similar exercises have been conducted since the Sept. 11, 2001 terror attacks.
The exercise will be rescheduled if there is bad weather.
