Charlotte Douglas International Airport is investigating incidents involving commercial aircraft that occurred recently, according to airport officials and the Federal Aviation Administration.

One incident involved an American Airlines aircraft and a ground vehicle that crossed in front of the plane, according to reports from the pilot. The airport confirmed the incident is under investigation but provided limited additional details.

A separate incident occurred around 12:10 a.m. local time on Tuesday involving a UPS aircraft that aborted its landing approach as the jet neared the runway, according to the Federal Aviation Administration. Audio recordings captured communications during the incident, with references to questioning the actions of another aircraft or vehicle.

The Federal Aviation Administration is reviewing both incidents as part of standard safety protocols. Charlotte Douglas International Airport, one of the busiest airports in the United States, handles hundreds of flights daily.

Both incidents appear to involve potential runway or taxiway conflicts, though specific details about the circumstances and any safety risks have not been fully disclosed by authorities. No injuries have been reported in connection with either incident.
