$50M In Diamonds Stolen In A Minute

Earlier today in Brussels a group of 8 men cut open a hole in a fence at the airport and then drove up to a plane that was headed to Switzerland and stole $50M worth of diamonds from the plane before making a successful getaway. The robbery was obviously meticulously executed, but what gets me is how easy these people got on to the airport grounds and how easily they managed to get close to a plane. What if they had been terrorists? Apparently it is pretty damn easy to walk up to a plane.
