With a sharp LERX, the F-16 regularly pulls a nice vortex on each side as it maneuvers hard. Getting a shot of that is not a surprise. However, I have recently been slowly making my way through shots from RIAT (months after the event) and I was working through some shots of the Belgian F-16 display. I came across a shot of the jet pulling and rolling, taken from astern of the aircraft. I noticed a second, smaller vortex trailing from the tail plane. It appears that, with differential tail for the roll, there is a vortex coming from the tail plane – possibly at the route. This pleases the old aero guy within!
