Is anyone else annoyed, perhaps irrationally, by titles containing 'no one (else) knows why'? This has been used so abusively in the past that I think my tolerance for it lowered quite a bit.<p>The cause for the meltdown seems somewhat clear from the article itself, the electrical system hasn't been designed properly and while the exact specific problem hasn't been found, I wouldn't say it's quite 'no one knows why'.
