Kogalymavi Flight 9268: "Explosive."

That is the consensus today. That is what Prime Minister David Cameron stated the cause of the crash  today. And the Egyptians. Terrorism? ISIS reiterated its claim of responsibility today but said it would reveal how they brought the plane down in their own time. ISIS' previous claim was discounted. Ruptured fuel tank? Not ruled out but today the US said it had intercepted phone communications that implicated ISIS.
