Frank Mishak and his wife Marlys from Clear Lake, Iowa honored the memory of their son Sgt. Blaine A. Mishak Saturday, October 26, 2012. Twenty years ago on Monday October 29, 1992, 12 Army Rangers and Air Force special operations troops perished in a helicopter crash just north of Antelope Island. On Saturday, their families, friends and those who helped with the rescue and recovery celebrated their memory with a rededication of a monument on Antelope Island. The crash of the Air Force MH-60G Pave Hawk helicopter, was the last chopper in a four-helicopter formation that was carrying Army and Air Force special operations troops from HAFB to the Army's Dugway Proving Ground as part of a training exercise.
