Fog - the great leveller
Looks like someone important won't be getting to bed early. Challenger (presume RAAF) from Canberra missed at YMML, tried YMEN, circled some more and just landed at YMAV with the vis somewhere between 900m and 100m (consecutive METARs)
PS I'm not really a plane spotter - just stuck in Sydney wondering if I'll end up in Melbourne or Brisbane - the two possible alternatives VA have given me....
