When the U.S. military took the extraordinary step of grounding its entire fleet of V-22 Ospreys this week, it wasn’t reacting just to the recent deadly crash of the aircraft off the coast of Japan. The aircraft has had a long list of problems in its short history.
The Osprey takes off and lands like a helicopter but can tilt its propellers horizontally to fly like an airplane. That unique and complex design has allowed the Osprey to speed troops to the battlefield. The U.S. Marine Corps, which operates the vast majority of the Ospreys in service, calls it a “game-changing assault support platform."
