Yes, but they're always down to Bingo 2 (Dilithium crystals) - I blame the Air Engineer's crap CRM for merely muttering "Cap'n, she canna' take it...." whilst James T gives it some at Warp Lots, instead of playing a more positive part in the team... As a result, they always have to divert to some obscure planet teeming with nasty Things - which is invariably bad news if you're a black mate in a red shirt! Always the first to go when whichever Thing living on said planet decides to get tetchy...
An Improbabilty Drive might be a Nice to Have option?
