[edit] Background
The existence of this contractor is not from aired dialog, but is derived from the text of the starship dedication plaques. It is a reference to The Adventures of Buckaroo Banzai Across the Eighth Dimension!, which, in turn, took the name from Thomas Pynchon's novel V. (Star Trek: The Next Generation Companion)
