inexperienced crews?
Just commenting on deSitter's observation a page ago making an assumption about the RJ's crew experience level. While the Airbus crew no doubt has more total time, I have to wonder if they are likely less experienced in type than the RJ pilots. For this type of accident, time in type may be the more important metric (having a feel for your dimensions, etc.)
A lot of airports that I fly to have wingspan limitations on selected taxiways. It will be interesting to see if considering such limitations is part of the response to this incident.
