On: Why aren't black box flight recorders better?

It doesn't need to keep recording after a crash, and really, just a few seconds after the event that precipitated the crash is all that's necessary (I've watched every episode of Aviation Disasters).

Necessary for what? I was thinking more along the lines of giving us more raw data to be able to better deduce where planes might end up post-crash.

It’s not necessary after the crash. It’s necessary for after power failure. These are not the same thing.

[WalterBright → ComputerGuru]

Necessary for determining the cause of the accident.
