Ann Romney said the air scare she had last week happened so fast there wasn't time to panic and recalled the details of the flight diversion, resulting in her plane making an emergency landing in Denver.

"I was just watching a movie and I could see out of the corner of my eye there were a lot of hustle and bustle going by me," Ann Romney told Jay Leno on the Tonight Show, "and all of a sudden my movie goes off and I turn around and I look at everybody and I'm like 'oh, there's smoke in the cockpit and there it was.'"

She explained her husband's subsequent comment afterward at a fundraiser when he joked that he didn't know why the windows on the plane don't open.

"It's his way of making light of how worried he is about me," she said. "It's his way of dealing with the panic of knowing how dangerous this was."

Mrs. Romney appeared for the first time on the sofa of the late-night host and also revealed that after she-amid criticism over her husband's campaign last week-said in an interview on Radio Iowa, "stop it. This is hard," that she at first thought she might have gone a little too far.

"I stepped out of the interview and I was like, 'oh dear, was that a little strong?'" she recalled thinking. She said since though "everyone I've seen has given me high fives."

Leno asked Mrs. Romney about the videotape of her husband's saying the 47 percent comment made at a closed-door fundraiser. She called the aftermath "frustrating."

"it's very frustrating thing because you try so hard to get your message out," she said. "You don't like those things to get misinterpreted as to what, why we're running and how strongly I believe and how important it is to what Mitt can bring to this country."

She added, "we care about the 100 percent."

Mrs. Romney said that four years ago she made a video tape and on the tape she looked into the camera and said, "Mitt, this is for you, sweetheart. I'm never doing this again."

She showed her husband the clips and he quipped, "you know, Ann you say that after every pregnancy."
