The fairings that cover the flap tracks

Ah, I see. I didn't realize how much the flap track/hinge protruded
underneath.

It seems to me that the canoe-style fairings were not implemented until
maybe 15 years ago, because I don't remember seeing them before 15
years ago. Did the fairings used to be small and hidden below the flap?
And then evolved into extending well beyond the flap?
