Yeah, that raised my eyebrow also.

I'm in Australia, tangentially connected to the Fugro vessel ocean floor search that followed and almost from the outset heard very little other than "pilot appears to have evaded radar, swung plane about low, and gone waaaaay off course delibrately".

Various 'causes' have been hypoxia, hijacking, suicidal pilot | other flight crew - sans any real knowledge of happenings in the cockpit it's a standing mystery.
