A fire and rescue truck approached a blaze Tuesday at the Chippewa Valley Regional Airport, spraying a flaming tray from a safe distance. The fire was part of an airport emergency exercise that involved multiple fire departments in the Chippewa Valley. Nearby, maintenance supervisor Todd Norrell observed his staff go through the mock disaster drill. “The training is great for all our employees,” Norrell said. “It gives them the perspective of how to approach the aircraft. It’s a good hands-on experience to sharpen our skills.” Airport director Charity Zich said a realistic plane fuselage used during the training comes from Arff Specialists in Superior. The metal mobile aircraft trainer has doors that open and a luggage department.
