Between Sept. 28 and Oct. 15, Boeing will be flight testing a self-protection system aboard an Australian Wedgetail Airborne Early Warning and Control aircraft. Seven of the flights will be over Hood Canal.

During the testing, which will occur in the morning and afternoon, flares will be released from the aircraft, which is a 737-700 with Royal Australian Air Force markings.

The flares burn out within five seconds, but people could see white light and some smoke, a normal part of the activity. The aircraft also will be followed by a T-33 jet videotaping the tests for later analysis.
