[Mitt Romney] "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. So it's very dangerous."

Also very dangerous: installing roll-down windows in airplanes, the cabins of which depend upon precise levels of air pressurization to keep passengers and crew members from passing out due to lack of oxygen.

Then of course we had Romney in New Orleans after hurricane Isaac asking where the water came from:

I appreciate the chance to be here. I have a lot of questions for you. I’m here to learn...Did the water come from the sky, or the rivers, or the ocean?

And then there was Romney waxing idiotic about Michigan:

Everything seems right here. You know, I come back to Michigan; the trees are the right height. The grass is the right color for this time of year, kind of a brownish-greenish sort of thing. It just feels right.
