The Qantas aircraft landed in the same fog that the Virgin aircraft landed in. And in a very similar fuel state. i.e. f@ckall.
The QF aircraft landed at 0945 with the calculated ability to hold until 1020 and then commence an approach with reserves intact. So it landed with 1 hour left in the tanks, probably 30 minutes more than this incident in Perth landed with. However both aircraft overlooked the TAF Tempo requirement and did not have the 1 hour needed for that particular requirement, as the diversion was unplanned and observations were used instead of the TAF that both crew had.
