On Tuesday, a tragic plane crash involving a UPS cargo aircraft occurred in Louisville, Kentucky, resulting in the deaths of at least 11 people, with officials warning that the death toll could rise. The aircraft, a McDonnell Douglas MD-11, was attempting to take off when it crashed, sparking an urgent investigation to determine the cause of the disaster. Investigators are now examining dramatic video footage from airport security cameras, along with the aircraft’s crucial black boxes—the cockpit voice recorder and flight data recorder—both recovered from the wreckage on Wednesday.
The footage captured during the ill-fated takeoff appears to show a fire erupting near the left wing of the plane, specifically where one of its engines would normally be located. As the plane accelerated down the runway, the left engine seems to detach from the wing, a fact confirmed by Todd Inman, a member of the National Transportation Safety Board (NTSB), during a press briefing. Additional video and still images from the scene suggested that the engine could be seen sitting just off the runway after separation. This engine detachment likely contributed to the ensuing catastrophe.
Further complicating the situation, the video also shows flames shooting from the engine at the tail of the aircraft shortly after the left engine’s apparent failure. It is believed that debris from the detached left engine may have been ingested into the tail engine, potentially causing damage or malfunction. With the loss of one engine and possible impairment of the second, the aircraft would have struggled to generate enough lift to take off, particularly given that it was heavily loaded with cargo and fuel.
The MD-11, while designed to be capable of flying with one engine out, was faced with an almost impossible challenge in this scenario. The plane was traveling at nearly 200 miles per hour down the runway, with limited runway length remaining to abort or stop. Losing two engines in such critical moments would drastically reduce pilot options and control. Moreover, the detachment of the engine would have significantly altered the aircraft’s weight distribution and balance, making stable flight even more difficult. The severity of the fire and any subsequent damage to the wing would have further compromised the plane’s structural integrity.
At the time of the crash, the MD-11 was carrying an estimated 20,000 packages and approximately 255,000 pounds of jet fuel, destined for an eight-and-a-half-hour flight to Honolulu. The large quantity of fuel and cargo added to the complexity and danger of the situation. The intense fire that followed the crash burned for more than an hour at the industrial park where the plane came down, likely fueled by the jet fuel and surrounding materials.
The black boxes, critical to uncovering the events leading to the crash, were recovered from the tail section of the aircraft. This location is typically the most survivable section in a crash and the standard place for housing these recorders. According to Todd Inman, while the recorders experienced heat exposure from the fire, they were not physically breached or damaged by intrusion. These devices are specifically engineered to withstand extreme conditions, including temperatures reaching up to 2,000 degrees Fahrenheit for at least one hour.
Once secured, the black boxes will be transported to the NTSB laboratory in Washington, D.C., where investigators will analyze the data. The flight data recorder will provide detailed information about the aircraft’s performance and systems in the moments leading up to the crash. The cockpit voice recorder will reveal the dialogue between the pilots, their communications with air traffic control, and any warnings or alarms they might have heard. Inman indicated that it would take several days before the data can be fully reviewed and understood.
CBS News aviation safety analyst Robert Sumwalt, a former chair of the NTSB, emphasized the importance of the black boxes in the investigation. He noted that, in addition to analyzing the recorder data, investigators will examine the plane’s maintenance and inspection history to identify any mechanical issues. Pilot training records will also be scrutinized to assess the crew’s preparedness and response during the emergency.
The black boxes are bright orange to facilitate their recovery after accidents. Their outer shells are made from hardened metals such as titanium or stainless steel and contain internal insulation that protects the sensitive electronics inside. Although jet fuel typically burns between 800 and 1,200 degrees Fahrenheit, the fire at the crash site may have reached even higher temperatures due to the materials in the industrial park, creating particularly harsh conditions for the recorders.
