FedEx Corp., the world's largest cargo airline, has scrapped its order for the troubled Airbus A380 jumbo jet and said it would purchase 15 Boeing Co. 777 jets instead. It was the first cancellation of an A380 order. FedEx, working to meet international shipping demand, scrapped the 10-plane Airbus order after production troubles delayed planned deliveries from January 2009 into 2010. Probably wise anyway. Airbus is a fine aircraft; it’s just that this and this and this and this worry one a little. And did you ever see Tom Hank’s Cast Away?
