Highly innovative! Instead of their sudden death being a complete surprise, they may have had a few awful moments of warning.

The engineer who worked on it said it would provide only milliseconds of warning before the hull collapsed. He was promptly fired.

    Found this article [1] about the employee where this "millisecond warning" is mentioned. It's been in most media on the past few days. And yes, one has to wonder about a warning system that does not warm in advance and which operates in situations where no-one can do anything about it, anyway...

    I'd be more interested in a source that shows that such a warning system could give a usable warning timeframe at great depths under the sea.

  Just enough time to hear the "Bu" from "Buzz"

    I had to check if sound travels fast enough. Just about, yes. Half a millisec to go 1.5m.

  Better than being crushed like their CEO.

Wouldn't they have communicated that back if they had? There wasn't even an "Uh-oh", as far as we know.
- tverbeure 3y ago
  It takes longer than a few milliseconds to say "Uh-oh", probably.

  I remember seeing in the news that it is possible they released the ballast before the implosion, according to the findings, and they may have done that because of a warning

    In which case the fired engineer could have been off by orders of magnitude, and the crew actually had multiple seconds in which to feel they might avert disaster as they mashed the X button on the Logitech game controller to release the ballast.

  James Cameron has been giving various interviews where he speculates they probably audibly heard the delamination occurring with enough time to cause them to drop the weights and try to abort based on what he's hearing from people in the know within the circle of deep sea explorers involved in the search and rescue. None of this validates using the audio sensor as a warning system because whether you have milliseconds or as much as a couple of minutes warning prior to rapid decompression makes no difference at the depth it occurred, but it does suggest the passengers knew they were doomed prior to the actual decompression.
  - sangnoir 3y ago
    > [...]minutes warning prior to rapid decompression Do you mean rapid compression (i e. implosion)? The internal pressure in such subs is kept at roughly 1 atmosphere at all depths. The massive pressure difference at depth is why hull integrity is of the utmost importance, if it's compromised, things go south rapidly.
