"Deadly Osprey Crash Prompts US Military to Ground Entire Fleet"

The US military has grounded its entire fleet of Osprey V-22 helicopters following a fatal crash off the coast of Japan that claimed the lives of eight Air Force Special Operations Command service members. The grounding comes after a preliminary investigation suggested a materiel failure, rather than crew error, as the cause of the crash. This incident has raised concerns about the safety of the Osprey, which has been involved in multiple fatal accidents since its introduction. Japan has also grounded its fleet of Ospreys. The investigation into the crash is ongoing, with attention focused on the aircraft's unique design and mechanical issues, including a long-standing problem with the clutch.
