Somebody asked how many served on Kirk’s Enterprise . The answer is “around 400.” I forget where I know this from, but it must be common knowledge because a google search with “Kirk Enterprise 400 crew” turns up a number of hits. There are a few below, and they all refernce the 400 number, so it must have been mentioned somewhere authentic

(Kirk’s Enterprise was a Constitution-class starship, just like Decker’s Constellation. All such ships have a crew of about 400.)
