Re: Chekov, put on a red shirt!
Sadly he didn't. And just what is it with the command structure in these films? Scotty becomes CE out of nowhere in the first film, and he doesn't have a replacement so that the 17 year old navigator has to take over? Geez...
I guess it makes a little more sense than a guy going from a cadet on academic suspension to full on Starship Captain in about a week.
