The recent air crash of Germanwings Flight 4U5925 raises
several questions. One that particularly irks me is why we still spend millions
of dollars trying to decipher audio on damaged cockpit voice recorders (CVRs)? A CVR can be invaluable but there is no doubt a cockpit
video recorder would have been faster and easier to interpret. In some cases,
the audio signal is not clear enough to even use. So why are we in a sense
still flying blind? Could it be economics? I rather doubt this. Compared to the total expense of a new airliner, the additional cost would be nominal. Could it be that airlines don't want us to know all the questionable behavior that goes on inside the cockpit? Gee, I wonder if that is it?
