Captain Yelland: This is the captain, I am speaking to every man aboard this ship. In the past few hours many things have happened; rumors of nuclear attacks and a third world war are totally untrue. We have no reason to believe that any aggression has been taken against our homes our families. I believe what we stumbled across is not man-made but a phenomena of nature, one that can't be explained. This phenomena is the storm in which the Nimitz went through less than 18 hours ago, the storm has had some effect on time as we know it, it created a portal, a door into another era. Today is December 7, 1941... I'm sure we are all aware of the significance of this date in this place in history. We are going to fight a battle that was lost before most of you were born. This time, with God's help, its going to be different... Good Luck.
