If you woke up to an usually loud noise in the QCA Thursday night, KWQC can tell you what it was.

Officials with the Quad City International Airport confirmed an engine "run-up" was happening just after 10 PM.

An engine "run-up" is done to determine the performance of an aircraft engine. The maintenance started about 10:10 PM and lasted about five minutes.

But KWQC has been hearing reports of another series of loud "booms" in the Clinton County and northern Scott County region. Viewers heard the noises on Tuesday and Wednesday.

KWQC found out that some natural gas pipeline maintenance is to blame for those sounds.

A representative from "Enterprise Products" said the maintenance was done in order to clear the pipeline of propane. The company rep said that this type of maintenance can be very loud and the noise can carry for miles.
