That’s surprising that the black box overwrites itself after 2 hours of recording. This article linked to an article I missed about how the plane that had the door/panel fall off had the cockpit audio overwritten because it wasn’t collected in time.
The black box isn’t like a modern hard drive, with terabytes of storage. They’re often old, and even the modern ones need to put so much effort into protection against things like fire, seawater and collisions that they don’t have as much space as you might imagine.
They have to rely on someone going out of their way to take the box out, or shut down the plane, because the alternative would be for them to have some way to decide for themselves to stop recording. If they could do that then a false positive would cause them to miss potentially important data, so they’re designed to keep going until someone makes it stop
That sounds like something they need to improve on then. Two hours is a ridiculously short amount of time given the tech we have in 2024.
