Just looked again, the ground spoilers did not start to deploy, and the rotation rate was that of a planned go around. Definately made before touchdown. Probably due to high rate of descent/windshear, but i wasn't on the stick that day, so pure speculation.
If that was the case and they didnt have the spoilers armed then why go all the way to touchdown before going around?
Wouldnt it be more effective just to do a normal GA?
