999.553 atm means roughly 10km depth, as it's ~1atm per every 10m of water above you. Yet depth on MULE interface is listed as 7135m. So why the 999.553 number? 713.553 would be just as good for puzzle. And I admire your geographical effort
. Off the coast of Chile, on such big shelf, nice
Other stuff about pressure is more "dynamic". It looks like the grenade is RGD-5. Fatality radius 3m, injury 25m. No way Charlie's diving suit would remain intact after an explosion in 5m diameter room, with grenade less than 2.5m from her. Not to mention the onrush of ~700 atmospheres of water and subsequent nuke. Even if it went off while she was at the surface (doesn't look like that from the cinematic), she would still be in trouble of that sonic wave. I don't know how much in trouble, but intuition tells me a nuke going off is very, very loud, and sound carries in water very well. I found
this paper but I'm not nerdy enough to actually go through it and calculate how much trouble she is.
Primitive tech/organics being able to contain ~700atm pressure differential doesn't seem possible either.
This is of course stuff that most people will not notice or care about.
Why does the heli at the end have it's gear lowered? It's above water, clearly has floats, why lower gear?
