This was either group suicide or murder. I've been diving for 30 years. Rescue and deep dive certified. These divers were effectively dead the moment they went in the water. At 150 feet, with recreational gear and without special gas mix, you're already dead. I'm an absolute madman adrenaline junkie. My hard floor is 120 feet. There was no possible way they were coming back, whether they panicked or not. That dive plan was never going to end with any of them alive.
