 In the scene in which Jinx asks the NASA computer about launch  possibilities (the second scene involving Jinx and the computer), as  the computer monitor rapidly flashes data on the screen, a couple of  hidden messages are included, but only for one or two frames each.  On the display of the shuttles main engine, the caption reads  "Space Shuttle Main Engine (SSME) burns liquid hydrogen & liquid  oxygen fuel (as if anyone didnt know that, I must say...)" The next  frame features a message saying "Dont get down on the DSK thrust  factor, man". And the following frame displays a message saying  "Three SSMEs are on the orbiters aft end, which is driving  (@27,000 Knm) me quite mental". (The messages are references to  Martin Short (qv)s character "Ed Grimsley", who was popular on  _"Saturday Night Live" (1975)_ (qv) at the time the film was being  produced.)
