War is good for the arms business. So a long and bloody civil war in Syria is just what arms manufacturers want. And while arming the Syrian government is fairly easy, how do you get weapons and ammunition to the Syrian rebels? The New York Times maps the flow of arms through an almost Sankey-like diagram where the number of flights determines the width of the arrows from source to destination.
And while that would be sufficient information to warrant a map, the Times adds a further layer by showing when the flights arrived. Clearly the civil war began with a certain number of arms. But as the war has both drawn on and become bloodier, new weapons are needed and ammunition needs to be restocked. Those needs likely explain a recent surge in flights.
