Shy, yes, ISTR there was no requirement for nitesun in RAFG - it was done well because it was all we had and probably didn't stop to think how freakin' dangerous it was - which compared to normal RNF, it probably wasn't
It wasn't until my fourth SH tour that the term "RNF" was invented; definitely no Nitesun back then. But the LSs
were recce'd with night landing aids laid out by a dedicated ground team....
.......and some of us are still required to do it like that these days - I'm sure you'd soon get used to it again as a corporate pilot.
