HENRICO COUNTY, Va. -- Smoke coming from a luggage tractor outside Richmond International Airport entered the airport's air handling system, setting off the airport's fire alarms, airport spokesman Troy Bell said. There was no disruption to air traffic Thursday morning, he added.
"Aircraft Rescue and Fire Fighting believes [the] tug mechanically overheated, saw radiator fluid leak," Bell said. "TSA closed checkpoints briefly as a precaution.
Some travelers commented on social media that the smoke from the fire was preventing them from getting to their gate.
