[PSUBS-MAILIST] Titan submersible missing at Titanic site

[Alec Smyth via Personal_Submersibles]

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.
