On July 24, 1979 two fire trucks were involved in two separate accidents within 20 minutes of each other while responding fire alarms triggered by thunderstorms. Three firefighters were injured in the accidents.
The New Franklin GMC engine overturned on rain slicked Pa. 316 near I-81 at 4:30 p.m. injuring all three firefighters on board. The rig was responding to a AFA at Nichols Discount Store when the driver lost control and veered to the right. The engine struck a utility pole and rolled several times. All three were treated and released. The engine involved was a 1966 GMC previously owned and operated by Fayetteville Vol. Fire, the rig was a total loss.
Seventeen minutes after the first accident the Chambersburg ladder truck struck a traffic signal at the intersection of Lincoln Way East and Sixth Street while responding to an AFA at the Chambersburg Middle School. The truck was able to remain in service.
