Loss of situational awareness is a really bad deal, partly because you can be pretty far gone by the time you realize that things aren't right. The fact that there were cues present to tell them that they weren't where they thought they were (i.e. dme was too far off, tower giving them a low altitude alert, 117.1 instead of 109.9 tuned in both navaids, whatever FMS information they had available, strong ident for H-U-B instead of I-H-O-U {whatever that ils ident is, don't know off the top of my head}, etc etc etc) just means that the accident could have been averted if the cues had been reconized. Most accidents could be averted, if the error chain had been broken at some point, and this thread is correctly identifying places that it could have been broken. Sadly, neither of these guys was able to do that.
(edit: as far as the GS goes, someone above suggested that the crew may have interpreted a fast/slow flag as a GS indication... I haven't flown a Gulfstream but it seems plausible. They apparently were unfamiliar with the presentation, wanted a GS, found something that looked right, and went with it instead of confirming.)
What can we learn? That no matter how experienced you are, you still CAN make terrible mistakes. That the basics like tune-identify-monitor matter every time that you're in IMC, even when everything else is laid back & relaxed. That using all available tools to confirm your position isn't just for the "tough" situations but for every flight. That there's no substitute for being proficient in the aircraft you're flying today... and if you're a little "off your game" for whatever reason (tired, unfamiliar layout, been off for a while), then it's doubly important to pay attention to everything you have to make sure it's all working like you think it is.
And, if things don't feel right, stop pressing on at full speed in spite of it, but instead slow down and get reoriented so that you KNOW your actual position is where you need to be, instead of hoping for the best.
Remember, nobody is "so good" that it can't happen to you.
Wow, note that the VOR ID is "HUB" and the localizer is "I-HUB"....what a trap that is, jeez!
