Yes. People seem to think the bends always happens on exposure to weird pressures, but it just doesn’t. I guess they’re understandably imagining it’s the same as hot or cold.
(though no idea about the effects on the human body from such a sudden change)
Well, enough delta p is entirely capable of squishing an entire person through a thumb-sized hole, and while there’s no hole here I image there’d still be some sort of shock wave, and the air already in your lungs returning to normal volume suddenly would be uncomfortable. Don’t go too deep the first time, definitely ease into it.
Interestingly just 1 atm is fairly harmless. The first time someone got caught in a vacuum chamber they weren’t sure what they’d find, but the guy just got up and said his ears hurt.
Iran isn’t directly mentioned. Vague terms like “the North” appear, and historically many American evangelicals have identified the USSR with it, because that was the geopolitical bogeyman of the day. I’ve had older evangelicals insist to me that Russia borders Israel as a result.
Iran’s more plausible than Russia, but if we pretend for a moment it’s not all some desert guy’s mushroom trip it could just as easily be Turkey.
