So by your expert calculations the Virgin guys would have been landing with less than FFR on the first attempt.
If thats the case why not land?
Why go around and run a serious risk of flaming out only to have to land in the same weather 10 mins later?
Gazumpy both planes descended below the minima because they had to.
Qantas got visual and landed. Virgin did not get visual and went around.
You dont know what Qantas would have done if they were not visual.
Virgin landed the second time without becoming visual because they had to.
Whats your beef?
