Update: Apparently, Mitt was joking
At a $50,000/ticket fundraiser at the Beverly Hills Hilton (home to one of the great Trader Vic's of America, I might add), Mitt Romney expressed his controversial views on aerospace engineering, as recounted by the LA Times's Seema Mehta:
Romney’s wife, Ann, was in attendance, and the candidate spoke of the concern he had for her when her plane had to make an emergency landing Friday en route to Santa Monica because of an electrical malfunction.
“I appreciate the fact that she is on the ground, safe and sound. And I don’t think she knows just how worried some of us were,” 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. So it’s very dangerous. And she was choking and rubbing her eyes. Fortunately, there was enough oxygen for the pilot and copilot to make a safe landing in Denver. But she’s safe and sound.”
I expect that's the sort of insight into technology that Romney acquired while creating jobs by remaking American industry to be more efficient.
