At the very end of the live-stream for the nominal SpaceX STP-2 mission, the presenter places what appears to be a baseball cap onto the table. It reads "NORMINAL" (sic).
My first thought was how embarrassing, they mixed up the spelling of "normal" and "nominal", but as English is clearly harder than rocket science, I'm turning to the appropriate authority on such matters.
Is "norminal" a normal word? If so, what does it mean?
