First time I thought someone had thrown a rock into the river when I heard the large splash.
Next time I saw the flash of silver through the air, spinning, triple twist with Pike as it took the fly.
Saw more than a couple of dozen quite large flying anti gravity fish in less than a quarter of an hour at the point where the river Bovey enters the Teign before I got bored and went on my way. Forget fly rod and line, just hold the frying pan out.
