With some air accidents incinerating the wreckage at very high temeratures as a result due to a hot fire, both the cockpit voice recorder (CVR) and the flight data recorder (FDR) will take a toll, and the recoverability of information may simply not be there in the end. Granted, both of these can take some real punishment. No argument.
But a recent example of such an incident occured in Western Norway just this week. A BAe 146-200 crashed belonging to Atlantic Airways. The cockpit voice recorder and the flight data recorder were badly damaged in the hot fire that followed the crash, and may never reveal what was really communicated among the pilots or what happened to the aircraft. It is still being analyzed, but in advanced laboratories.
In this day and age with really advanced technology and satillite communication, would it be an option to simply have the "Black Boxes" of a modern aircraft "hosted" on the ground on a dedicated server or in a fcaility somewhere? I do not see how this could be too much of a challenge for the right and bright mind out there with the right technology available. I am only considering new aircraft of tomorrow.
Gone should be the days searching for that box that may never be found on the ocean floor, or not be in shape to provide the answer or the reason for an accident.
