Movies are for entertainment, documentaries and histories are for enlightenment. I recall the Midway episode of Victory at Sea where the narrator said Nimitz deduced that the Japanese would strike at Midway next, it was Operation Magic that let him prepare for the assault. The unglamorous-and crucial- role of maintenance and support people is rarely shown. The Yorktown was badly damaged in the battle of the Coral Sea, limped back to Pearl Harbor, went into drydock on May 28. The drydock inspectors said the ship would need at two weeks of repairs and three months would be better, Nimitz said "We need this ship back in 3 days."
