 The inquiry report was submitted to Fargo on 20 April.The court made several findings, including that Waddle failed to take positive action in response to the non-availability of the AVSDU, nine of the 13 watchstations in and around the control room were manned by substitute personnel, and that one of the sonar operators was unqualified to stand watch.The court also issued numerous opinions, including that the accident was caused by "a series and combination of individual negligence(s) onboard "Greeneville"," "artificial urgency" by Waddle to rush the submarine through its demonstration schedule as it began to run late, failure to follow standard procedures, the abbreviated periscope search, distractions and obstruction caused by the presence of the civilian guests, crew training deficiencies, overconfidence and complacency, and Waddle's not paying enough attention to ship contact information.
