Does this mean we will soon be seeing flocks of migrating F-18's going south like geese?

So THIS is what V formations of migrating birds have known all along. They use the vortices of the one in front to make their efforts easier. I always wondered about that and other than some lame explanation about following in the lead bird's "wake" for less "drag" there was never any explanation from normal sources. I admit that I never looked into it further than PBS though.

NASCAR's follow in "wakes" for less "drag".... not birds. This video shows me a much more plausible reason the birds use the V formations.
