Could someone please explain why they searched an area "twice the size of Connecticut" looking for the sub and spent four days searching the planet when the Navy HEARD the explosion when it happened, knew exactly where it happened, and everyone knew the sub was diving on the Titanic? Why didn't they just concentrate those resources right in that spot where the Titanic was from the start and find the wreckage the same day it happened? Something doesn't add up here and I have not heard any logical explanation.
Lieutenant : "Admiral we think we heard an explosion in the area where that sub is diving on the Titanic at exactly the moment when they lost contact with the sub. But we're not sure."
Admiral: "Very well. Start a search area twice the size of Connecticut immediately!"
