Gidday apache.
Remember one dark and stormy night when we lost RAIM just before the FAF on a certain South Coast RNAV approach? Missed approach followed by the NDB to minima, then a circle to land in black drizzle over a featureless ocean onto final, without slope guidance! It's the unexpected ones that get your attention. C'mon mate, you do miss it don't you.
The bummer was, it was my leg!
