In Charlotte, one veteran is sharing stories of his time spent with McCain. 

Colonel Quincy Collins, a retired U.S. Air Force colonel, was a prisoner of war for nearly eight years during the Vietnam War. He says at one point during his imprisonment, he shared a cell with McCain. 

"John and I got to going right quick with what we're going to do to keep the morale of the troops up, because that's all you had," Collins says.

He says they would organize performances for the other troops to help keep their spirits lifted. 

Collins says McCain always wanted to serve his country, and his legacy is best remembered in his own words, forever inked in the novel "We Came Home."

"One of the most important things in life, along with a man's family, is to make some contribution to his country. John did that. And he will forever be remembered for that," Collins says reading from the book. 

Collins made such an impact on McCain, he is briefly mentioned in McCain's book "Faith of My Fathers".
