The Big Question: why has the UK so far been unable to find the suspected British Islamic State killer and the group’s hostages?
Because the world is a large place. It may be in the unfashionable western spiral arm, we may all be so deluded we still think digital watches are a pretty neat idea, but it’s still a pretty big place.
And why haven’t we managed to find MH370? Its somewhere in a massive ocean that we have only partially mapped and not explored at all. The world is a huge place.
