Ten aircraft were inside the Monmouth Municipal Airport hangar when a fire broke out early Friday. The city reported eight of the planes were destroyed and the other two were damaged.
The fire department said no one was injured.
The cause of the fire is not known. The city said the Illinois State Fire Marshall is investigating.
The fire department said it was called to the airport at 5:54 a.m. on a report of heavy smoke coming from the administrative office and hangar. Upon arrival, the department found the hangar fully engulfed in fire.
The department said it took three hours to contain the scene. Around ten other fire departments responded to a mutual aid call to help the Monmouth department.
The city’s website said its airport is the oldest continually operated airport in Illinois.
