Check out these two animations.
First one is all fedex aircraft (non-feeder) in a 25 hour period. Amazing! Memphis looks like an anthill!
Second one is an animation of diversions around severe weather around KMEM. Neat to see them sneaking in between the cells.
BTW, if this hasnt been mentioned before, these are both from the Alexis Park Inn website, with a GREAT collection of aviation videos.
