The McDonnell Douglas MD-11 cargo plane, built in 1991, went down around 5:15 p.m. Nov. 4, 2025, after its left wing caught fire.

The federal investigation into last year's fatal UPS plane crash in Louisville showed one of the key defects found on the plane's failed engine was a known issue among Boeing's service team, albeit one Boeing didn't believe would lead to a "safety of flight condition."
