You ought to see what happens backstage during a theatrical show.
I really enjoyed holding 20 actors, 15 crew, 200 props, 400 lights with 1000 light cues, and 300 sound cues together against the onslaught of Murphy's Law - and doing it eight times a week.
We had the luxury of being able to hold the house for a few minutes at the start, but once we heard "Cue one - Go!" there was no turning back.
(The closest I ever got to stopping a performance was when it appeared that we had a fire on stage. I was in full "get ready inform the audience, and put them into evacuate" mode when the ASM said that it was just a smoke machine that had gone nutz.)
