-14,15 Plane leaves finger for second attempt to take-off.
-14,24 Ground control clears plane for take-off.
Wonder what happened in those 9 minutes.
Were they rushed or distracted?
Any timepressure on them for the schedule?
My money is on a configuration error, but then again, 9 minutes is short but not too short.... 3 minutes for startup and 6 for taxi.
I guess it must be relatively easy for the investigators to rule out.
