Also of note:
Homendy said the cockpit voice recorder did not capture any data because it had been overwritten and again called on regulators to mandate retrofitting existing planes with recorders that capture 25 hours of data, up from the two hours required at present.
It’s probably important to establish when the crew noticed anomolous pressure readings. Did they continue the flight after sensors indicated a problem? Did the crew follow procedure after the failure, and was that procedure sufficient to protect passengers and crew?
These investigations are usually centered on whether there needs to be a change in procedure, training, maintenance schedules, and design. It’s not like they’re trying to pin the blame on a pilot pressing a mysterious “eject door plug” button.
There’s another bit of information that this particular plane was restricted from flying to Hawaii because it had had frequent alarms in previous flights that would indicate a cabin pressure problem. This was not a “sudden” thing.
Yea, only 9.807 m/s^2. Just imagine if the craft was flying over Jupiter. Uranus is a little gassier, butt imagine flying over Jupiter.
