I don't think the fact that the controller was wireless gets highlighted enough. Bluetooth devices have a hard time working above sea level and you're expecting it to work 3800m below the surface. Delusional.
BT devices got problems only when water is in between anetna1 and antena2. It does not matter at what altitude the devices are, just what is inbetween them.
I mean, the sub had reached Titanic several times, right?
So even without the design documents, we know it was previously capable of operating at depth.
Which we means we know the hull wasn't made of cotton candy, we know it wasn't propelled under water by an internal combustion engine, and we know it wasn't controlled by a device that stops working in water.

What if they command something in the water? Have you seen the design?
If you want to command something in the water, you run a wire from that something to a receiver in the cabin.
Right, exactly. Or for a "sub" that only holds 5 people... maybe just spend the 10 cents and wire it lol.
