The Economist:
"A rush to judgment, irresponsible comments from the government and three separate investigations are not going to do much to restore flyers' confidence in the Pakistani government's ability to safely regulate its airlines. Pakistan's state-owned flag carrier, Pakistan International Airlines, was barred from all EU airports for eight months in 2007, so it's clear that international air-travel regulators haven't had the highest opinion of Pakistan's aviation sector in the past. So far, the chaos following this incident—the second major crash near Islamabad in as many years—is only making the Pakistani government and its Civil Aviation Authority look worse."
