1 critical, 3 hospitalised after fatal Marine Corps crash

The fatal crash of the Marine Corps' new hybridised airplane-and-helicopter aircraft during a training exercise in Hawaii over the weekend is renewing safety concerns about the machine.
But the Marines say the MV-22 Osprey has proven itself to be very safe despite high-profile accidents early in its operation.
The MV-22 Osprey went down Sunday at a military base outside Honolulu with 21 Marines and a Navy corpsman on board. The crash killed one Marine and critically injured another. Three Marines were still hospitalised in stable condition yesterday.
The governor of Okinawa in southern Japan immediately called for all flights of Ospreys to be suspended in his area until the cause of the crash is determined. The US operates 24 Ospreys on Okinawa and announced a week ago that 10 more would be deployed to Yokota Air Base near Tokyo beginning in 2017.

The Osprey that crashed had taken off from the USS Essex, a Navy ship that was 160 kilometers offshore. It was flying to Oahu to drop off infantry Marines who were to train on land, said Capt. Brian Block, a spokesman for the 15th Marine Expeditionary Unit.
The crash, which the Marines initially called a hard landing, didn't stop the unit's exercises, Block said. The Marines also don't plan to ground their fleet of Ospreys.

"We're continuing to train in order to make sure we remain sharp and ready for whatever comes up during deployment," Block said.
The unit, which is based in Camp Pendleton, California, recently left home for a seven-month deployment to the Pacific and the Middle East.

Built by Boeing Co and Bell, a unit of Textron Inc, the Osprey program was nearly scrapped after a history of mechanical failures and two test crashes that killed 23 Marines in 2000.
Those crashes prompted the Marine Corps to put a lot of effort into training pilots and eliminating sources of risk, said Loren Thompson, an analyst at the Lexington Institute, a think tank based in Virginia.
The aircraft also has features that make it safer than normal helicopters, like rotors that automatically collapse on landing to reduce the dangers of a hard landing, Thompson said.
The Osprey has deployed to Iraq and Afghanistan since its introduction to the fleet. The Marine Corps has been using it in the Himalayas this month to help with earthquake disaster relief in Nepal.
