Just saw it on CNN. Interesting on Xwind limits for various operators. We are a very large Airbus operator in America and our 320/319 Xwind limit is 29kts. We include all of the gusts when computing the Xwind. Also cannot land with a reported loss of airspeed of greater than 15kts. As one can see, we are conservative which is ok by me.
On extremely Xwind days, my personal technique is to take out a little of the crab prior to the flare. It appears in the vid that most of the rudder was applied at touch down. On short final I like to remind my crew member and more importantly myself a go-around is always an option...sometimes we forget that in the heat of the battle.
