On Tuesday evening, a McDonnell Douglas MD-11 cargo plane destined for Honolulu crashed near UPS Worldport in Louisville, Kentucky, killing all 14 people on board, including three pilots.
The MD-11, built in 1991, was carrying 38,000 gallons of fuel when it crashed into two buildings. The crash caused large fires and thick smoke, as shown in images from the scene.
Following the tragedy, UPS announced on Friday that it would ground its MD-11 aircraft, which constitute about 9% of its fleet.
"We made this decision proactively at the recommendation of the aircraft manufacturer. Nothing is more important to us than the safety of our employees and the communities we serve."
FedEx, operating 28 MD-11s out of approximately 700 aircraft, also decided to ground its MD-11 fleet while conducting a thorough safety review based on the manufacturer's advice.
"Out of an abundance of caution, we have made the decision to immediately ground our MD-11 fleet as we conduct a thorough inspection and safety review."
Both UPS and FedEx emphasized that the decision to ground the MD-11 planes was made to prioritize safety and act responsibly following the fatal incident.
