SD89,
That is because as humans, nothing is ever entirely our fault. Life would be so much better if the word "but" never came after "yes," . In this case the accident was caused by the moving pilot. The conversation should not be a "yes, but" conversation it should be a "yes, this was my fault. May we please do what we can to see it doesn't happen again? Landing on adjacent pads always demands caution. Why was my normal level of caution not sufficient in this case?" One thing I can't understand is why nobody involved in parking aircraft didn't look at what they were routinely doing and point out it was not a good sop for the obvious reason. Having said that, what they did is still not the cause of the accident. Had the second ship already landed and then they rolled out the other one and rolled it into the moving blades, then it would have been the fault of the ground handlers.
