This episode explores the case of Lieutenant Commander Edward Henry "Butch" O'Hare who was lost during a night fighter mission on 26 November 1943.  LCDR O'Hare was a Medal of Honor recipient credited with destroying five Japanese aircraft in a single battle a year before he was lost.  When O'Hare's Hellcat fighter was last seen he was over the Pacific Ocean about 60 miles from Tarawa; however, he is officially considered an "Unresolved" casualty from the Battle of Tarawa in the Defense POW/MIA Accounting Agency's database.  Debate rages to this day whether LCDR O'Hare was shot down by a Japanese aircraft or he was a victim of "friendly fire".  In any case, this hero is one of almost 73,000 MIA's from World War II.
