(Yes, this is a variation on the carriers at Pearl Harbor thread.)
On the morning of December 7, 1941, the USS Enterprise was supposed to be back at Pearl Harbor. However, due to rough seas, the Enterprise was delayed and, luckily, missed being among those ships sunk at Pearl Harbor when the Japanese attacked. (Some of her planes were shot down in the attack, by a combination of both Zeroes and friendly fire.)
So, WI the Enterprise came back as planned and was sunk at Pearl Harbor (the Japanese would likely go after it as well)?
