Well MD11 would be one type Iīm absolutely sure of (and have experienced) that hates crabby landings!
And the Scarebus is not meant to be landed without decrabbing to a certain extent either as quoted from the OM-B before.
Somebody just messed up the landing during the EY-incident - nothing more, nothing less. The Xwind certainly sound do-able on the size of an A345.
But cīmon - AUH-JFK! - is near the red line.
There, but for the grace of God...
