It's interesting that the report doesn't even mention crew alertness or fatigue.
They reported at 1830L and pushed at 2008L. The accident happened at 4 in the morning after a long duty. 0400 is the perfect time of day for some suboptimal decision making (same time of day as the flydubai) - and may well explain the lack of gumption when it came to alerting authorities of their ploughing activities.
