ST. LOUIS — All U.S. and Missouri flags at government buildings statewide will be at half-staff Saturday to honor a soldier who died in a March helicopter crash.

Army Officer Rusten Radford Smith, of St. James, Missouri, was killed along with eight others when two Blackhawk medical evacuation helicopters crashed near Fort Campbell, Kentucky.

Flags will be at half staff on the day of his funeral.

Army Officer Zachary Esparaza of Jackson, Missouri, was also killed in the same crash. Another order to put Missouri flags at half-staff to honor Esparaza at a future date is expected from the governor’s office.

“Rusten’s life was cut tragically short, but he gave it in patriotic service to our nation, which he so loved, and we are forever grateful for that service,”stated Governor Parson.

The Associated Press reports that the HH-60 Black Hawk helicopter crashed on March 29 near Fort Campbell during a nighttime training exercise. Brig. Gen. John Lubas, the 101st Airborne deputy commander, said the accident occurred while the helicopters were flying.
