Tammy Duckworth was flying high as a combat helicopter pilot in Iraq - until her aircraft took at direct hit from a rocket-propelled grenade. She survived, but lost both of her legs. Today she is an assistant secretary at Veterans Affairs, where she works to aid other wounded vets. She spoke to CNN's Don Lemon about her experience, and what the VA is now doing to help heal the wounds of battle - both physical and mental. A special Web site aims to reach vets even if they live far away from a VA facility.

CNN's Don Lemon interviews Princeton University's Dr. Cornel West about his new memoir, "Brother West: Living and Loving Out Loud."

Seniors dealing with health problems, loneliness and chronic pain still go to the airport most days, sometimes in the middle of the night, to greet U.S. troops and say "thank you" on behalf of the nation. Their story is now told in a new documentary film, "The Way We Get By."
