Gul dukat,
Life is a little different down there. When the radar is not present and the radionavaids are out all you need is CAVOK and when it's dark, believe it or not, some lights. In this case I think he must have seen our lights so we continued on the INS to the field and descended to our minimum safe alt. When we overflew the field, still on the INS, we must have woken him up with the engine noise. He came on the radio and asked us what was up. When we explained him that we must have missed the field he came back with the magic words: "Oh I think I'll switch on the lights".
It worked.
