I recall as a controller an A340 from an airline just North of the US missing out twice on the RWY 13 IGS at Kai Tak, then making 2 missed approaches at Macau (which was just recently completed), heading off towards ZGGG, getting to around TAMOT, declaring a fuel emergency, and then we gave him a PAR monitored ILS onto RWY 31 with about 20 knots tail wind and vis about 300 meters. First we in the tower saw of him, was him vacating 31 at about A3. They were pretty quiet!
