ATLANTA – Delta Air Lines has faced a series of unsettling incidents recently, including smoke or haze in the cabin on two flights and a separate crash that injured more than 20 people.

What we know:

Delta Flight 876 was forced to return to Hartsfield-Jackson Atlanta International Airport on Monday morning because of “haze” inside the aircraft.

According to Delta, the flight crew followed procedures, declared an emergency for priority handling from air traffic control, and returned to Atlanta after the haze was observed.

Upon landing on Runway 27, emergency slides were deployed for egress.

The Boeing 717, which departed Atlanta for Columbia, South Carolina, at approximately 8:30 a.m., was carrying 94 customers, two pilots, and three flight attendants. Delta teams arranged ground transportation and rebooking for passengers.

According to the registry information for the aircraft involved, the Boeing 717 was declared airworthy on Sept. 16, 1999.
