Andy Probert designed the
Enterprise D, and owns the designs to the Enterprise.
Paramount is using his designs with permission. You can
see Andy in "Encounter at
Farpoint", in the post-atomic court. Andy is
the spectator wearing "a giant tribble", actually a very
large fur hat.
The original Wright plane was
named.....BIRD OF PREY!
and "Liaisons" are
the only episodes in TOS, the movies, and TNG which has
no scenes filmed on the bridge.
The "Star Trek: The
Next Generation" Technical Manual (Pocket Books, ISBN
0-671-70427-3) is the complete technical guide to the
Treknology used in TNG. It is written by Rick Sternbach
and Michael Okuda, who work in TNG's Art Department.
Among their responsibilities include making sure that
everything is consistent in the technical department
from show to show.
One of the controls not
seen is the "Infinite Improbability Generator", a
reference from the "Hitchiker's Guide to the Galaxy"
stock footage is used to save money...so to those who
thought the Klingon ship in Heart of Glory looked
familiar, it should. The footage came from ST:TMP.
