Apparently she had an interesting career beforehand, too.

Technically “safe for work” (no nudity), but interesting nonetheless.
Enforce or disregard the Prime Directive, whichever is more advantageous to your current situation.
Indeed! And I'd forgotten that she had that small part in Get Smart!.
IIRC, Ms. Pettyjohn made a bit of money at the sci-fi conventions selling photos of herself wearing a "diminished" version of that Drill Thrall outfit.
Had she lived, I'll bet she would've turned up in one of those "New Voyages" fan films. Quite a few of the TOS guest actors did.
