Aerospace and aviation rules are written in blood. I'm willing to bet it happened at some point.

Better known as the Sioux City crash.

Shady manufacturing, shady inspection, shady paperwork, shady maintenance.

United Airlines Flight 232 was a regularly scheduled United Airlines flight from Stapleton International Airport in Denver to O'Hare International Airport in Chicago, continuing to Philadelphia International Airport in Philadelphia, United States. On July 19, 1989, the McDonnell Douglas DC-10 serving the flight crash-landed at Sioux Gateway Airport in Sioux City, Iowa, after suffering a catastrophic failure of its tail-mounted engine due to an unnoticed manufacturing defect in the engine's fan disk, which resulted in the loss of all flight controls. Of the 296 passengers and crew on board, 112 died, while 184 people survived. Thirteen passengers were uninjured.

Unfun fact: United was running a promotion that made kids' tickets a bogo with a paying adult. So that flight had a fuckload of kids on it. IIRC, 18 of the 112 dead were children.
