Schwoebel, in 1999, published a book titled "Explosion Aboard the Iowa" on his experience directing Sandia's investigation into the explosion. In the book, Schwoebel concluded that, in his opinion, the "Iowa" incident and aftermath illustrated that high-consequence incidents should be investigated by an independent group instead of by a self-assessment, as had occurred with the U.S. Navy investigating itself in this case. He also observed that abuse results when a powerful organization attempts to manipulate the press, as the U.S. Navy had apparently tried to do through leaks of information about the investigation. Furthermore, Schwoebel noted the unfair and indiscriminate recitation by the press of the sensational material leaked by the U.S. Navy. Finally, he observed that the U.S. Navy was lacking a due process in military justice as it related to deceased personnel. Also in 1999, Charles Thompson published a book, titled "A Glimpse of Hell: The Explosion on the USS Iowa and Its Cover-Up", documenting his investigation into the explosion and its aftermath. The book was extremely critical of many of "Iowa"s crewmembers, as well as many of those involved with the subsequent U.S. Navy investigation, and the NCIS (formerly NIS). Thompson stated that after the book was published, a previously scheduled invitation to speak at the U.S. Navy's National Museum was rescinded, his book was banned from being sold in the museum's book store, and Navy exchange stores at bases throughout the world were forbidden from selling his book. Alan E. Diehl, a former safety manager for the U.S. Navy, described the USS "Iowa" incident in his 2003 book "Silent Knights: Blowing the Whistle on Military Accidents and Their Cover-Ups". Diehl called the incident and its aftermath the worst military cover-up he had ever seen. An of the TV series "JAG" was based upon the incident. On 19 April 1991, the Hartwig family sued the Navy for "intentional and negligent infliction of emotional distress" under the Federal Tort Claims Act. On 30 June 1992 the Hartwigs added another count of emotional distress to the lawsuit, after the Navy sent a letter to Hartwig's parents inviting the dead sailor to join the U.S. Naval Reserve. The Hartwigs sued for emotional distress in order to avoid the limitations imposed by the "Feres" Doctrine. The DoD asked for a dismissal of the Hartwigs' suit on grounds of sovereign immunity, but in May 1993, US District Judge Paul R. Matia ruled in Cleveland that the Hartwigs' suit could proceed.
