I find it hard to believe that someone can get to this stage in their career and feel that a 14 knot tailwind on a wet (and not overly long) runway at night is an acceptable risk.
Yes there are restrictions on them circling, but there are other airports too. Did they not consider diverting?
Sure the regulator, the airline and the crew all had a hand in this, but the PIC is the final filter. An avoidable accident.
