I have some written report of an a340 windshear incident in HKG, didn't realize it was Virgin.
What I remember is that there was a typhoon some 200nm away, and windshear alearts were present, extra fuel uplifted.
The first approach was abandoned because of a windshear encounter at some 500'.
After some time in the hold, a second approach was started.
The tower issued a windshear alert of -25kt at 3 miles.
Now you have to know the LLWAS system in order to understand what happened: the systems gives out first-encouter-max-strength alert, which means if you have a medium shear at 3 miles and one more severe at 1 mile, you will get the alert that the crew got.
Sure enough, the encountered some shear at 3 miles, but it was moderate and the approach continued, believing they had passed the reported shear. Then at some 300', they encountered the big one.
The captain, who was the PF, executed a recovery maneuver (as far as i know a340, its just pullng all the way back and opening max power), and they recovered at 80' AGL, and diverted to their alternate.
This is just from memory, I will have access to the full report when I get back home in a few days.
