This is the video of the talk given at Tactical Training Croup, Atlantic about April 1993, after having conducted certification of most all of the Atlantic Fleet NSSMS units. LCDR Don Diehl had sat through the Court of Inquiry, having been sent TAD from the USS GEORGE WASHINGTON as COMNAVAIRLANT’s subject matter expert on Combat Direction Center (CDC) Operations. Rather conducting a oral board on the operators on the ships, Don basically told the story of what happened, interspersed with questions of the people who manned the various stations to check their knowledge. In this manner, he helped convey the circumstances, so the other crews could learn from the mistakes. Don has since passed away, but he was a great inspector and instructor for the team across the several months we spent traveling the world together.
