There has been enormous focus on the returning to stand to fix a minor error as if this is the cause!
Although likely not the direct cause, any time an unusual or extraordinary situation intervenes with a departure, and then an accident does occur, it should not be ruled out as a possible
contributing factor. Did they perhaps fail to recalculate the numbers after the 1hr+ (?) delay ? Not get the current ATIS ? Were all the remaining electronics functioning ? Etc., etc.
Many times we have seen that the end trap consists of little things along the path. Swiss cheese.
