767 lands !!!!
Happened last week:
Aircraft with 235 pax and 9 crew is lined up on ILS, weather Cat3, remaining fuel at or below required minimum. Airport has electrical power problems: rvr and wind info no longer available. Aircraft therefore instructed to go-around, crew then declare short of fuel and emergency situation imminent. ILS officially downgraded to Cat1. All other traffic diverts. ATC clear aircraft for Cat1 approach although weather remains Cat3. Crew commence approach, at final approach fix ATC informs that rvr below Cat1 minimum. aircraft however continues, but does not receive landing clearance. Just before touchdown crew asks for and receives clearance to land.
Guess the operator and airport...
