He should have had a submersible sub... With a support ship... And we could add in some safety divers and a chamber too... Okay, sarcasm off... You guy's would die down there... You are way over thinking it.. You don't play around, You go... I'm guessing , because I don't know him.. It went some thing like this... Mass air leak behind his head... Time for me to go... Adds some air to bc so it's a free assent ( No swimming ) and no extra air needed to fuel the body... keeps the assent rate in check to not cork... Shoots off his SMB and swaps to his pony when the back gas goes... Blows off any safety stop because he never went in to DECO and the SMB was in mono-filament line and felt safer up top...
