After a Delta flight made an emergency landing in Atlanta​ in February, a maintenance crew found there was barely any or possibly no oil in the aircraft's right engine, an NTSB report said.

A Delta flight taking off the Atlanta Hartsfield/Jackson International Airport in Georgia reported smoke filling the cabin and cockpit in February, according to a preliminary report from The National Transportation Safety Board.

Delta Flight 876 was forced to return to Atlanta and undergo emergency evacuation after smoke filled the cabin and cockpit shortly after takeoff; two passengers suffered minor injuries.
