What the fuck did Logitech do wrong here? If anything, that controller was the most functional part of the sub
Put it in a bag of rice and it probably still works! Assuming it's still whole.
It's not. When the sub collapsed, it did so with the energy of about 50kg of TNT.
This is why there will be no attempt to recover the bodies either. There just isn't anything left.
Fascinating. Where did you get those numbers, I'd like to read more.
W = p Δ V
The Sub had a Volume of the 142 cm (56 in) internal diameter, 2.4-meter-long (7.9 ft) carbon fiber-wound cylinder
so 3.8m³ of air, should be about 3.8m³ x 4x10⁷ Pa = 152x10⁶ J, 152MJ
TNT has about 4.2x10⁶J/kg, so I get about 36kg of TNT.
But I ignored the front and back Domes, which will add a bit, and possibly have other issues as well, so the ballpark should be right.
I got them from this Scott Manley video: https://www.youtube.com/watch?v=qdz9vcSFBqw
He explains that the energy contained in a vessel is equal to the difference in pressure on the vessel wall, times the volume of the container.
