On February 24, 2025, a Delta 717 aircraft carrying 94 passengers and five crew members made an emergency landing at Hartsfield-Jackson Atlanta International Airport after thick smoke filled the cabin and cockpit. The National Transportation Safety Board (NTSB) has released preliminary findings on this serious incident, raising important questions about airline safety, emergency procedures, and the ongoing use of older aircraft in commercial fleets. This article provides a detailed, step-by-step account of what happened, how the crew responded, and what the NTSB’s investigation means for passengers, airline employees, and the broader aviation industry.
What Happened on Delta Flight DL876?
Delta Air Lines Flight DL876 was scheduled to fly from Atlanta, Georgia 🇺🇸, to Columbia, South Carolina, on the morning of February 24, 2025. The aircraft, a 25-year-old Boeing 717, took off at about 8:48 a.m. local time. On board were 94 passengers, three flight attendants, and two pilots.
About 35 minutes after departure, the situation changed dramatically. Thick, gray smoke began pouring from the plane’s ventilation systems, quickly filling both the passenger cabin and the cockpit. According to the NTSB’s preliminary report, the smoke was so dense that the lead flight attendant could not see beyond the first few rows of seats. The pilots, unable to see their controls clearly, immediately put on their emergency oxygen masks—a standard safety measure when smoke or fumes enter the cockpit.
How Did the Crew Respond?
The crew’s actions during the emergency followed strict aviation safety protocols. Here’s a breakdown of the steps they took:
– Flight attendants tried to alert the pilots using the emergency call button on their jumpseat phones. When there was no response, they made announcements over the public address system, hoping the pilots would hear them through their headsets.
– The lead flight attendant then knocked directly on the cockpit door to get the pilots’ attention.
– By this point, the pilots had already noticed the smoke, donned their oxygen masks, and declared a mayday emergency with air traffic control.
– Cockpit alarms sounded, including a master caution light and a smoke detector alarm in the forward lavatory.
– The pilots focused on keeping control of the Delta 717 and returning safely to Atlanta.
The aircraft landed back at Atlanta at about 9:00 a.m., just over 10 minutes after the smoke was first detected. Emergency vehicles were waiting on the runway.
The Evacuation: What Passengers Experienced
Once the Delta 717 came to a stop, the captain opened the cockpit door and was met by what he described as a “blinding wall of smoke.” The decision was made to evacuate the aircraft immediately.
- All 94 passengers evacuated using emergency slides and exits above the wings.
- Passengers were told to leave all baggage behind to speed up the evacuation—a standard safety rule in emergencies.
- Two passengers suffered minor injuries during the evacuation, but both were treated at the scene and released. No one was seriously hurt, and there were no reported cases of smoke inhalation.
The quick and orderly evacuation was a direct result of the crew’s training and the cooperation of passengers. According to analysis by VisaVerge.com, such outcomes are a testament to the effectiveness of regular emergency drills and clear safety briefings.
What Did the NTSB Find?
The National Transportation Safety Board (NTSB) began investigating the incident immediately. Their preliminary findings, released in May 2025, provide important details:
- The right engine of the Delta 717 had “no visible oil” when inspected after the emergency landing. This points to a possible mechanical failure related to engine lubrication, which may have caused the smoke.
- The NTSB confirmed the timeline of events reported by the crew and validated the emergency procedures followed.
- The investigation is ongoing, with a full report expected in the coming months.
The NTSB’s role is to determine the cause of aviation accidents and recommend changes to prevent future incidents. Their findings are used by airlines, manufacturers, and regulators to improve safety standards. For more information about the NTSB and its investigations, visit the official NTSB website.
How Did Delta Air Lines Respond?
Delta Air Lines issued a statement after the incident, commending the crew for their professionalism and quick thinking. The airline said:
“The flight crew followed procedures to return to Atlanta when a haze inside the aircraft was observed after departure. Nothing is more important than the safety of our customers and people, and we apologize to our customers for the experience.”
Initially, Delta described the incident as involving a “haze” in the cabin, but the NTSB later clarified that it was “thick smoke.” Delta has fully cooperated with the NTSB’s investigation and has not announced any immediate changes to its maintenance or inspection procedures. However, the airline may take further action once the NTSB’s final report is released.
Why Are Incidents Like This So Serious?
Smoke in an aircraft cabin is one of the most dangerous situations in aviation. It can:
- Make it hard for pilots to see their instruments and control the plane.
- Cause panic among passengers.
- Lead to breathing problems or even unconsciousness if the smoke is toxic.
- Force crews to make quick decisions about emergency landings and evacuations.
The Delta 717 incident shows how important it is for crews to be well-trained and for safety equipment—like oxygen masks and emergency slides—to work properly.
What Safety Procedures Were Followed?
Several key safety protocols were put into action during this emergency:
1. Oxygen Masks for Pilots
– As soon as smoke entered the cockpit, the pilots put on their emergency oxygen masks. This is a standard procedure to protect them from smoke inhalation and keep them alert during a crisis.
2. Multiple Communication Attempts
– Flight attendants used every available method to contact the pilots, including emergency call buttons, public address announcements, and direct knocking on the cockpit door.
3. Emergency Evacuation
– The crew ordered an immediate evacuation using emergency slides and over-wing exits. Passengers were told to leave all belongings behind to avoid blocking the exits.
4. Coordination with Emergency Services
– Atlanta Fire Rescue was on the scene as soon as the Delta 717 landed, ready to assist with the evacuation and provide medical care.
5. Use of All Available Personnel
– An off-duty flight attendant on board moved to an emergency exit to help if needed, showing the value of having extra trained personnel during emergencies.
What Does This Mean for Passengers and Airline Workers?
For passengers, this incident is a reminder of why it’s important to pay attention to safety briefings and know where the nearest exits are. In an emergency, seconds count, and leaving personal items behind can save lives.
For airline employees, the Delta 717 emergency landing highlights the importance of regular training and teamwork. The crew’s ability to stay calm and follow procedures made a big difference in the outcome.
