ATC there are very aware of the problems caused by the hangar adjacent to the TDZ and if there is a hint of turbulence or shear it will be notified on the ATIS. I have not read the report but am guessing that there was no such comment on the ATIS. Did the crew report the turbulence at the time or to the investigators at some point down the the track?? I did see a pic of the damage and it ain't pretty.
