3:14 / 14:18 The TITAN Cyclops 2 can send PING's back to the surface mothership:
The communications that they have . . . They do not have any radio communications because radio waves do not go through the water. They have a rudimentary system which is like a SONAR system. The vessel sends a PING back to the [mothership] vessel every 15 minutes, and within that PING, they can send very short text messages like the old text system that we had before smart phones.
4:10 / 14:18 The people being able to breathe . . .:
What they have on board, they have air for about 4 days. And also, they have a scrubber system similar to what they have on spacecraft. That converts CO2 back into breatheable air. They also have backup scrubbers. They also have, for final emergencies, SCUBA tanks beneath the floorboards.
4:41 / 14:18 Drinking water . . .:
One of the things that has not been mentioned, is how much water they have. The human body can only survive about 3 days without any water. . . They each only took along a canister of water. The dive itself was meant to last about 8 hours. 2.5 hours descent; 3 - 4 hours observation at depth, near the seabed; 2.5 hours ascent. They lost communications around 1 hour 45 minutes.
