This video from 2009 would be cool enough if it was just an F-18 sucking up some gas from a KC-135, but it's more than that. It's a Blue Angels, F-18 sucking up some gas! Oh but wait, it gets even better... they're actually flying thru the tops of the clouds while the Blue Angels F-18 is sucking up some gas!
And to top it all off (no pun intended), the pilot has added some excellent voice over to explain a little about the refueling process. This is a must see video if there ever was one : )
