[PSUBS-MAILIST] Titan submersible missing at Titanic site

Hi Ala
- the question is not which controller your sub has.
The question is how many paying Guest you have..

Hi Doug,
my ambient sub had a game controller controlling speed, steering, ballast & 
a few other things. They have been tested and abused by several million 
kids. :) . But aside from that I had back up for all those functions so if 
it failed the sub still operated. And I am sure Oceangate would have done 
the same. ABS & DNV-GL have a principal that no one failure can cause a 
catastrophic event. Even though I have heard they weren't certified, they 
would certainly have been building to the rules.
All a bit strange as they were only half way to the wreck.
If the hull had have imploded it would have failed at maybe 1/4 of its 
crush depth. If power failed they would have gone to the surface, & should 
have had surface coms that would work with a back up battery.
Alan
