Harris Faulkner celebrated International Women's Day by interviewing Dr. Anna Lee Fisher, who became the first mother to fly in space as part of her trailblazing career at NASA. 

Dr. Fisher is the mother of Fox News correspondent Kristin Fisher and she told the story of how she flew a mission in 1984, a year after giving birth to Kristin.

"Timing is everything. I didn't set out to be the first mom in space, it just worked out that way," she said on "Outnumbered Overtime."

She explained that she was back at work for a pilots meeting just a few days after giving birth because she wanted her colleagues to know she would uphold her commitment to NASA.

Kristin Fisher, who reports out of the Washington, D.C., bureau at Fox News, said she appreciated what her mom did even more after she gave birth to a daughter a few years ago.

"It's hard enough going to Vietnam for a week to cover the president, I can't imagine what it was like for her being strapped on top of a rocket and being blasted into space with the real possibility in the back of your mind that there's a good chance you might not come back," she said.

Dr. Fisher said that "was the hardest thing I've ever done" and recalled her last phone call before departing on the mission.
