According to one dive computer, SAC had tripled and heart rate was up to 175. That was just before approaching the exit at Sue sink and making it out, for diver 2.
Not really surprising.
The father of diver 3 must have recognized they were in a bad situation after missing the planned exit. He began physically pushing and tossing his son (diver 3) ahead of him every time he caught up to him.
I may disagree getting themselves in this situation. But he deserves respect for this.
Hmmm…the video is no longer available.
Privated, hopefully to reconsider the narration.
