Not REAL close formation, but here are a few pix from a couple of weeks

Hard to tell his distance; did you shoot those with a 400 mm.

Offhand, though, it reminds me of how we Naval Aviators (a conceited
bunch) used to define an Air Force formation: "Two or more airplanes
going the same direction on the same day."
