Does anyone know why commercial air flight patterns coming into SJ Int'l Airport have changed in recent weeks? The new flight pattern has planes either flying over or east of Tulare Hill, or they fly in an odd cross pattern over the residential neighborhood west of St. Teresa Blvd before straightening out into the usual flight pattern toward the airport. Is this a gradual noise adaptation pattern in connection to the future power plant or is there something going on with the runways/number of flights that has air traffic controllers slightly altering the incoming flight pattern? Just curious....
