I would agree with another poster that having the ability to fly an NDB means your mind is working. If you can fly that accurately with strong winds then you can fly anything instead of slavishly following a GPS.
Regarding a PAR! I had an emergency years back which coincided with extensive unforecast fog.
the military base were colour code red but quickly sized up the situation and i was talked down in a twin breaking cloud at 80 feet with an RVR of 550 meters.
You could even see the fog hanging on the Hangar roofs.
Reaching minima the controller went through the usual chat of missing if not visual and then intensified the commands to cloud break.
those guys could talk you down onto the deck if need be.
but those were the days when military bases were open all hours
