CHARLOTTE, N.C. (CBS Charlotte) — Medics were dispatched to the Charlotte-Douglas International Airport last night, after smoke was reported inside the cabin of a US Airways plane.

Four crew members were medically evaluated and no injuries were reported.

The plane was parked at a gate when the incident occurred, and passengers had not yet boarded the flight.

Charlotte-Douglas officials are investigating the plane this morning, in an attempt to determine what caused the smoke inside the cabin.
