Airport crisis planning failures

From the BBC World Service: One of Europe's busiest airports has canceled more than 700 flights today as a disruption caused by snow and ice enters a sixth day. The problem was made worse because of a shortage of anti-freeze for de-icing planes at Schiphol Airport in Amsterdam. Dutch airline KLM is the main one affected.
