Stockton Metropolitan Airport officials are seeking a new air traffic control tower to address safety concerns and operational limitations. The aging structure has caused unexpected issues, including a recent incident where yellow jackets infiltrated the cab of the tower causing staff to evacuate during a busy Saturday of air travel. The new tower, which would be taller and located in a different area, is expected to address these deficiencies. The San Joaquin County Board of Supervisors has requested a federal grant to help fund the renovations. The airport is also expanding its operations, with additional cargo flights and discussions about introducing Los Angeles as a flight option for passengers.
