The Pentagon announced a service-wide grounding of all V-22 Osprey tilt-wing aircraft after one of the planes went down last week off the coast of Japan, killing all eight service members of the Air Force Special Operations Command aboard, the Washington Post reports.
Prior to this accident, more than 60 other crew have been killed in various accidents, including testing, involving the troubled V-22. Since the Osprey became operational in 2007, 33 people have died in operational accidents, with two happening in combat zones. Across the Pentagon, various services have more than 300 of the aircraft currently in operation.
