This article is spot on. An excellent description of the way traffic flows through airspace and the role of ATC in movement of aircraft. I can add that as a pilot is would be a bit disconcerting and unusual to be on an instrument approach into an airport and be handed off to the tower only to receive no response. This would likely happen with only a couple of minutes of the flight left and at a time when workload is high (assuming IMC conditions). There would probably be a little confusion before deciding to switch back to the previous frequency.

Not particularly dangerous - but the pilot does have to be prepared for handling some atypical tasks on an otherwise routine approach

Edit to note: VFR (visual flight - night or day) would be a non-event (from the pilot's perspective) with a sleeping controller so long as traffic is relatively light, as it would be at night most places

Yes, for a nearly deserted airport the tower controller isn't as important as people would expect.

The article doesn't mention it but I believe that the sleeping controller is also supposed to be handling ground control - planes taxiing and ground vehicles like fire, security, baggage, etc.

http://www.avweb.com/news/sayagain/191072-1.html has a (now retired) US air traffic controller's thoughts on a fatal collision involving two of the three planes a European controller was responsible for. It suggests that not all cases of sleep deprived controllers are harmless.

Like most serious accidents, the sleep deprived controller is just one part of what went ridiculously wrong there. Had the controller actually been sleeping the entire time, and the pilots followed the automated systems, it's entirely possible that they would have been ok. In addition, the equipment failure/downtimes severely limited any operator's situational awareness.

It's one of the cruel ironies here, that a completely passed out controller likely would have lead to a better outcome.
