Incident
According to the investigation, a DC-9 aircraft was observed by control tower personnel to take off on a taxiway. This observation was corroborated by radar data from the airport and a readout of the flight data recorder. The takeoff occurred just prior to the start of civil twilight in the morning.
Lighting and Markings
The runway features white centerline markings, white edge lighting, and white markings. In contrast, the taxiway had yellow markings and green centerline lighting. These differences in lighting and markings are standard for distinguishing runways from taxiways.
