If you hear loud noises overhead this week, the Oregon Military Department says there's no reason to be alarmed.



The 142nd Fighter Wing will be conducting routine night flying training exercises with the F-15 jet fighter on Tuesday through Friday. Most training flights, which are mandatory according to Air Force requirements, will be completed before 10 p.m.



Officials said the training could produce more noise than normal at the air base and near Portland International Airport.
