Before advanced autoland, perhaps FDRs and CVRs. could be added to decrease the mystery and investigation costs? If a traditional FDR isn't easily retrofitted, then a system that captures video of the majority of the controls and the entirety of the control panel would be enough? A high-def web cam and a single board computer in a tough box would likely suffice. Apparently all the NTSB has found so far is aluminum confetti.
