The soliders are returned to there Home town on commerical jets. The ones in the video are the ones that bring the solider back to the states.
I have a friend who's son was killed. I can't remeber which base they went to to pick up their son's body but... They than flew home on the jet that bought their son back here for burial. There also was a Marine accompanying the body. A honor gaurd and convey meant the plane. The family and body was removed first before anything or anyone else. The family was taken to the underside of the plane so they would be there when their son was taken from the plane. Once he was in the hearse the people on the plane left the plane.
