Everyone says that the wind must have been blowing pretty hard. Good pickup on the flag on the silo, but how about some hard evidence?
Go to the BOM site and to the weather charts page. Go to the bottom and find the analysis charts archive and bring up the 0000 and 0600 analysis charts for 14 August 2004. (Date the picture was taken).
Looks like a big front going through Brisbane from a low pressure system further down the coast. This would produce lots of wind.
So well done to the crew for what looks like a normal crosswind landing (provided to wind is from the right of the aircraft in the picture). If it is from the left then...........
