I think a problem accumulates and ends up breaking the atc comms and also the deck crew. Last night my sqn did an MP test in case 3 with over a dozen people. It just got progressively worse until nothing worked, including deck crew for launching. Repeated request for launch made no difference. Every so often the crew would wake up and direct someone onto the cat, but mostly they didn't. We tentatively think it's due to the atc comms on recovery getting overwhelmed and not clearing stale marshall slots. It also seems to assign the same bort numbers to multiple aircraft causing confusion. Comms get mixed up and stop responding. If the CVN transition from case 3 to case 1 it can leave some people stuck forever in case 3 comms even though the cvn is now working case 1.
