That's a fascinating wikipedia article you cited. Off-topic, but I was impressed by the caption underneath the FedEx aircraft that reads, "FedEx became the first U.S. carrier to equip its aircraft with an anti-missile defense system in 2006. The gray oval Northrop Grumman Guardian pod can be seen on the belly of this FedEx MD-10 between and just aft of the main landing gear."
Wow. If only Flight MH-17 had that stuff; really makes one think about airliners in 2014.
