Thanks COUNTrecount. It wouldn't have quite made it to Diego Garcia, but the claim is nonsense. The plane was shot down, IMHO, and was observed going down in a flaming mess in the South China Sea, probably shot down by the Chinese. I'd make a wild guess that every other airliner since has taken seriously the Chinese demand that they ask permission to enter the illegally claimed airspace. Not the nuttiest idea though:
