	The Enterprise is able to travel 1000 light years to retrieve the Captain in approximately 12 hours. This is a much faster speed than we have seen in previous episodes. It would make it possible for the Enterprise to reach Andromeda in a year and a half, whereas in "By Any Other Name" such a journey would have taken thousands of years.
	Kirk sends the landing party out to do a "detailed" analysis of the planet. Then they get together, report, and Kirk sends D'Amato out to look for water - shouldn't that have been part of the analysis?
	Sulu makes reference to the events of "The Devil in the Dark", even though he did not appear in that episode.
