doable. it's something we should definitely be doing research on. especially when you think about air france, it took two years to find that black box. these contain critical information to prevent future accidents. it seems something like this would make a lot of sense. >> one reason they explore e these accidents is to prevent the same mistake from happening in the future. if you wait four years, or whoever many years, that's a lot of flights that have happened without that information. >> i know the concerns here are when you have thousands of airplanes in the sky, you have to get that data information, but from a technical standpoint rgs we're not talking about streaming video that's hundreds of gigabytes at a time. >> speed, direction, whether the engines are on fire. is that really an overload? >> that's barely a megabyte of data.
