Families of four of the five Marines killed when their Osprey crashed in California in June of 2022 filed a federal lawsuit Thursday alleging that the aircraft's manufacturers failed to address known mechanical failures that led to the deaths.
The Marines were killed when their MV-22 Osprey experienced a catastrophic mechanical failure known as hard-clutch engagement, a known problem with the tilt-rotor aircraft that has happened more than a dozen times since 2010.
