You have to wonder how often, if ever, these re-surfacing failsafe measures are actually tested or replaced. For example, a parachute needs to be inspected and re-packed at least every 180 days under FAA regulations whether it is used or not, just to ensure it will function properly when needed. Smoke detectors and fire alarms need to be constantly tested. Brakes on vehicles need to used once in a while to endure they function. I would think the same principle would apply here.
I wonder if OceanGate just installed these re-surfacing devices 5 years ago and then left it like that.
