Thanks to a head’s up in the ClubColumbia forums, I found this interesting history of a Gulfstream (presumably a GV) flying out of Outagamie County Regional, Appleton, Wisconsin. I’m curious to know exactly what was being "tested" during this flight (an 8.5 hour one at that), but it sure took some fancy flight planning to get it worked out as it did!
Speaking of FlightAware, it is certainly one of my favorite sites to visit since it’sinception in March of ’05. I often listen to traffic flying overhead on my scanner from Atlanta Center, and I enjoy looking up the flights to see what type aircraft is being flown, where it originated, and where it is going. I encourage you to have a look!
