Drop in fraction of airports within a cluster regime.
Fc(q) is the fraction of airports belonging to a cluster regime c after removal of a fraction of connections q. The first frame shows a drop in airports that belong to the largest connected component based on an low traffic removal. The subsequent frames show the same for high traffic removal and an average over 500 random removals. In all cases, peripheral hubs (Cc = Cw = 0) drop out of the largest connected component first.
