5/6. Over 1,300 American pilots were declared missing in action as a result of the Vietnam War and the US Government has a mandate to search for all servicemen missing from all previous conflicts.
Nearly 40 years on from the conflict, a specialist unit of the American military (JPAC) revisits the site where the fighter jet of Major Herman Knapp and his co-pilot Lt David Austin was shot down while returning from a bombing raid over Hanoi. But with only 30 days allowed to excavate the site, can JPAC find the servicemen's remains and close the case?
