Ginger, thank you. A new look at a new docu-series, "1969" back to the groundbreaking year when woodstock, the stonewall yourising and Manson murders changed our country forever. The moon landing and now meet the women who helped make it happen. It's a half century since the age of aquarius. One of the most turbulent periods of the 20th century now "1969," a new ABC docu-series takes a closer look at some of the events of that year and has some of the unsung heroes of that golden age of nasa who happened to be women. Women were expected to stay home, take care of the kids, clean the house. I'm not saying I did that. My name is Margaret Hamilton. In 1969 I was building on board flight software for Apollo missions. Margaret Hamilton literally wrote the code 345 made the lunar landing possible and didn't know about these women at the time. At first I was the only woman that was hired to do on board flight software. The guy that I worked with when I first got there said, how can you leave your daughter at home? And I just said to him you do what's right for you and I'll do what's right for me. Reporter: It also features the real-life Katherine Johnson, a gifted mathematician who struggled to overcome discriminate nation at nasa was turned into the hit film "Hidden figures." Katherine is the gal for that. She can handle any numbers you put in front of her. At 53, the engineers asked for specific skills. The supervisor said, that's Katherine. Katherine was a leader in her area and paved the way. She made enormous contributions to calculations and the trajectory for the program. What happened if somebody questioned your work? Tough. This one is going to be great, "1969" premieres tonight at 10:00 P.M. Eastern right here on ABC.
