'We're running out of time': Operation Babylift adoptees return to Vietnam to search for family

As the world marks 50 years since the fall of Saigon and end of the Vietnam War, a group of adoptees who were taken out of the country prior to 1975 are racing against time to find the mothers they were separated from. An event spearheaded by Australian-Vietnamese adoptees saw a group of them embark on a bike ride to raise money for elderly Vietnamese residents and spread awareness of their ongoing search for family.
