The FAA is investigating into the incident, which follows another recent Delta mishap—a crash landing in Toronto last week.

A Delta Air Lines flight returned to Atlanta on Monday morning shortly after takeoff when the crew reported "possible smoke" in the aircraft, according to the Federal Aviation Administration, just two days after another Delta flight was diverted due to smoke on the plane.

A Delta flight carrying 94 passengers and five crew members left Atlanta Hartsfield-Jackson Airport headed for Columbia, South Carolina, before it was forced to return to Atlanta due to a “haze” in the passenger cabin.
