For those who are unaware: A couple billionaires, a pilot, and one of the billionaires’ son are currently stuck inside an extremely tiny sub a couple thousand meters under the sea (inside of the sub with the guys above).
They were supposed to dive down to the titanic, but lost connection about halfway down. They’ve been missing for the past 48 hours, and have 2 days until the oxygen in the sub runs out. Do you think they’ll make it?
Really? No redundancy on the controls? If anything along the chain fails, not even some emergency ascent lever?
Edit: plenty of redundancy - “If the remote fails, the propellers can be controlled through an internal hard-wire system, Newman said.”
