A Delta flight from Atlanta to Baltimore was forced to make an emergency landing on Monday after one of its engines failed in mid-flight, the airline confirmed to Business Insider.

The flight, DL 1425, had a total of 148 passengers on board, six crew, according to The Aviation Herald. It diverted to Raleigh-Durham International Airport in North Carolina and landed safely.

The MD-88 aircraft was over Virginia about an hour into its nearly two-hour scheduled flight time when it was forced to turn around, according to data from flight-tracking website FlightRadar24.

Initially, a spokesperson for Delta characterized the incident as minor and the diversion as precautionary, but has since confirmed to Business Insider that the plane's left engine failed.

Several social media users posted video a that showed what appears to be an orange glow from heat or flames. Business Insider has not been able to verify that the videos are authentic.

Delta confirmed on Tuesday that there was a "maintenance issue" with the left engine, which can be characterized as an engine failure. A spokesperson for the airline stated that the engine was replaced, and the faulty engine will be inspected by maintenance specialists.

The airline's initial statement read:

"The flight crew of Delta flight 1425 from Atlanta to Baltimore elected to divert to Raleigh, N.C. out of an abundance of caution after receiving an indication of a possible issue with one of the aircraft's engines. The flight landed without incident and customers will be reaccommodated on an alternate aircraft. We apologize to our customers for the inconvenience this diversion may have caused."
