the main argument touting the virtues of a 30 minute run dry proved to be useless in that accident
???? I think the main argument touting the virtues of a 30min dry run time was that it allowed continued flight for a while after losing all the oil. It was not a universal panacea for all transmisison failure modes. But the main main argument was that one should not strongly promote a product by making an important safety claim that one knows to be false. And the main question is, would the crew have followed the same path if SAC and its representatives had never mentioned 30min dry running time?
