FedEx cancels Airbus A380 order, switches to Boeing?

Basically FedEx got tired of Airbus saying that the A380 will be delayed again. FedEx ended up buying the 777F which is a good decision since the aircraft can hold a lot of cargo and only operates on 2 engines instead of 4 thereby making the aircraft more fuel efficient. The range on the 777F is also pretty good so FedEx can do more point to point flying instead of having to transport everything to 1 hub.
