Got this calendar for Christmas-- 'tis a beaut. If I made errors on the descriptions, correct them. My ego will go on. ;)
April's Ship: The unknown ship has illustrated on the starboard bow, USS Voyager. It appears to be modeled on a Runabout, but with short wings. It's a very cool concept.
A small correction -- The September picture showing the Captain's yacht arriving cannot be Picard's "first contact" with the Enterprise-D. We are shown in the TNG pilot episode (and in All Good Things..., too) that Picard arrived aboard a shuttlecraft piloted by Tasha Yar when he took command. Yes, it's picking a nit, but it's one of my best things.
