GOP presidential nominee Mitt Romney wowed a crowd over the weekend with his keen grasp of physics when he lamented that aeroplanes don't have windows, appearing to view it as a problem that could be fixed in jiffy with a patent and a couple of good engineers. Speaking about his wife's emergency landing Friday, Romney said: "When you have a fire in an aircraft, there's no place to go, exactly, there's no — and you can't find any oxygen from outside the aircraft to get in the aircraft, because the windows don'™t open. I don't know why they don'€™t do that. It's a real problem."
