This is what is called a 'cascade of failures' in aviation - and the term is used elsewhere. Multiple failures resulting in a catastrophic failure. In your own life and goings about, it's sometimes interesting to do a failure analysis and you'll often find you experienced a cascade. It's really unfortunate that the cockpit voice recorder was overwritten. I'm guessing they're using very old technology where storage space is at a premium. They're still using the flashing X on closed runways - e.g. at SEATAC right now. The lights looked incandescent a couple nights ago while passing the X. So not very bright or visible. This accident would probably have been one of the worst in history. Multiple passenger planes on the taxiway taken out by a passenger jet.
