Hundreds of passengers in a Dallas airport took a moment out of their travels to witness the return of a fallen Vietnam War veteran. Col Roy Knight Jr had last seen his family at this same airport 52 years before, when they came to say goodbye before he went to war. His return presented a rare moment of unity in the US, following a pair of mass shootings in Texas and Ohio that have shaken the country.
