BTW .. the protest in Japan is not only to do with a politic problem between US and Japan
The people know that this (hybrid) plane is prone to crash .. and the areas around the base are very populated !
The crash rate is no worse than many other novel concept aircraft such as the Harrier. The problem is that the Osprey is neither one nor t'other so the rotary guys don't like it and the fixed wing guys don't like it. Initially every chance anyone got they would run down the Osprey. Now its has been in service in war zones and it has not been falling out of the sky and been a sitting duck target as claimed. It has also operated in ways that no other rotary wing could by leaving the 'Gulf' area and self deploying to Libya where it was used in a downed pilot recovery and the pilot was back on board ship before normal rotary wing SAR would have reached him.
Unfortunately, the initial bad press scared off the commercial world and the Osprey was never taken through type certification for civil use. The initial intent was to use it as a regional turbo-prop equivalent operating without taking runway slots at busy airports but able to land on helipads in the middle of cities.
I have been amazed at how heated some people are in their dislike of the Osprey. However, I think that like the Harrier it will win its critics over - but it will take time.
