I'm not so sure. I mean, think about it. They spend months building this new engine. According to Torres, they test it 'molecule by molecule'. Everybody rejoices and is convinced this will get them home. Then Paris -not even an engineer- gets a bad feeling about it and runs a few simulations. All of which end in disaster. I mean, shouldn't they have run those simulations and discover these problems in a much earlier phase? Like, from before they even started building the engine, and when they were building the engine, continually refining them, rather than just 'the night before'?
