It's been 40 years since Randy Dalton's helicopter went down in the Vietnam War, and now his family will finally get some closure.  The Army Specialist's body will arrive at the Lambert Airport in St. Louis today then a motorcycle escort will lead him to Sunset Hill Funeral Home in Glen Carbon.  More than one thousand flags have been placed on the side of the road to honor the fallen soldier.  He will be laid to rest with full military honors at the Sunset Hill cemetery Sunday.
