Guess all you want. It was a mechanical error. I know 'conservatives' seemingly want to lay every plane crash at the feet of radicals, but a plane crash can just be a plane crash without Islamic 'conspiracies' you know.
Just basing my guess on recent history.
How many plane crashes have been caused by mechanical failures?
How many plane crashes have been caused by rabid Islamic lunatics?
If this plane crash REALLY was caused by a mechanical failure that wasn't Islamic-induced, it would be a TINY EXCEPTION to a VASTLY SUPERIOR RULE.
