That happens. It always annoyed me with Trek, too. Because they just used to write something like TECH in the script, and the production boys would do the rest. It meant that the writer didn't understand the danger, or the solution. And to me, that's bad writing.

No-one expects a writer to become an expert in fifty different disciplines to write a show, but from a story and character perspective, they do need to at least understand the basics of what is happening.
