Well, this blog post is more of a series of questions than opinions.
I read: Avoiding a Homeland Security Error That Could Leave the U.S. Flying Blind. This article talks about the pre-GPS system that is called Loran that is still used for geographical information by several US and foreign defense institutions and should be maintained/updated to serve as a back up when/if terrorists or other events interfere with our global positioning systems. Does anyone know anything about this?
What other behind-the-scenes systems should be kept? What systems need backups but don't have them? What is just obsolete? I guess this goes out to all my history of technology gurus out there! Can you help me? :)
