This from the article: When confronted with the falsified results, Ms Thomas suggested that in some cases she gave metal positive results because she thought it was "stupid" that the Navy required the tests to be conducted at -100F (-70C), - Could someone explain to me why the tests would need to be at that temperature as well. I also find it pointless as it is way below the freezing point of water and also most of the coldest parts of the world when surfaced.
