If you think RTOW had any part to play in that accident, then you don't get the point.
They could have waited 10 minutes, they could have used the reciprocal. A tyre failure of that exact pattern would have been just as disasterous, that day or any other. At any weight.
I fully agree that to turn a blind eye to limitations is unprofessional and unforgivable - but it did not cause this accident in this case. I am not saying that they were right to ignore a last minute change to RTOW (they were not) - just that this did not cause the accident and to place so much emphasis on this is to divert attention from the actual causes and the solutions.
