If you are reall interested in following up the debacle that the US airspace system has become, and the incredible way their controllers have been treated by the Bush Government, here are some links worth following:

The video link to the testimony yesterday is here (it is 3 hrs long, over 2 sessions - the second session is 3 air traffic controllers telling it how it is - the 1st session if a bunch of suits from the FAA pretending how good it is, except when the President of NATCA then shoots it all down in flames)

To see the extent of delays check this website every day or two - especially when a little bit if weather moves through

The FAA has gotten so far back on the curve with their controller recruitment and remuneration that it is now unrecoverable, except with a massive reduction in service provision.
NextGen and ADS-B are going to do nothing to solve the mess of the US NAS.
And this is not just my view - last month I spoke with controllers in the US NorthEast, and they are convinced - indeed they convinced me with compelling arguments, delivered with the same conviction you will see in the video of the testimony above.
