[PSUBS-MAILIST] Titan submersible missing at Titanic site

Another point: 

Older expeditions with guest to the titanic were done with two subs. So one 
can update/help/locate usw. the other. 
Seems the Mothership here has not even an Workclass rov at least.

The controller is not something I would use, mine is physically much 
tougher and has things like O-ring seals on all the pots and switches. 
Nonetheless, I found it amazing the degree to which the "experts" latched 
onto that and anything else that was off the shelf, as if the concept of 
using OTS components were some sort of cardinal sin. The controller, the 
cabin lights from Camping World, and recycled pipes for ballast were all 
treated as obvious evidence of bad engineering or even a total scam. Who 
cares what your ballast was in a previous life, if it weighs what you need 
it to weigh? Moving forward we not only have to look at whether OTS parts 
work and are reliable, but also how they will be perceived. I'm not just 
ranting against the misinformed TikTok experts, I think this is an actual 
lesson for us. Imagine a boat ramp conversation with some local authority 
right now, when you explain that you control the sub with a game 
controller.

  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.
