In the Apollo era, whenever there was a significant event about to occur, the flight director (I can recall the voice of Gene Kranz) would do a sort of go/no-go "roll call". He would call off names like "fido", "gido"(?), etc. (obviously shortened from a more meaningful title), to which someone would respond with a "go" (don't ever recall hearing a "no go"). Views of the controller room showed perhaps dozens of people; the director called off maybe 7 names.

What were the short names short for (what was the full title and scope of responsibility), and how was a room full of controllers organized so that only a short call-off list properly represented an over-all "go"/"no-go" status?

    $\begingroup$ The short list is a result of the fact that the front room controllers are actually the tip of a larger group of back room controllers as well. So, for example, the flight dynamics officer has a whole cadre of controllers that he communicates with as well. $\endgroup$

It should be removed, or you should add 1-2 block quotes from the source :). Not an attack on the content or on you, just the rules! $\endgroup$ Jul 9, 2019 at 18:28
