When I got home I traced out my route on Google Maps and realized I made a loop de loop. Whoa! I haven't heard that phrase in a long time. It used to mean making a vertical loop in an airplane. Now it mostly seems to refer to roller coasters. There was also a song with those words. This one is the closest to what I remember. There's no video, only a single still image.

While I am poking around I come across this video of five guys playing Grand Theft Auto with Hercules military air freighters. It's pretty amusing how much trouble these guys have just getting their aircraft lined up on the runway. They are trying for some formation flying but they don't get very far. One guy does manage to complete a loop
