In an instant unless OceanGate's patented monitoring system actually worked. If it did work, they would've had at least a couple of seconds to panic.
>Rush planned to pilot the sub himself, which critics said was an unnecessary risk: Under pressure, the experimental carbon fiber hull might, in the jargon of the sub world, “collapse catastrophically.” So OceanGate developed a new acoustic monitoring system, which can detect “crackling,” or, as Rush puts it, “the sound of micro-buckling way before it fails.”
I'm guessing these guys didn't even have a black box on this thing so we can't hear the last second of audio in the thing being a the CEO saying "Ohshi--" because his "you are about to die" alarm has gone off.

I don't suppose there is a huge line to license this technology.
