How about regional airport development? There are very busy and successful airports not far from the center of the universe in the South of the UK which are in desperate need of upgraded facilities. Tight budgets, environmental and space constraints along with short term business plans all conspire against their steady co-ordinated development.
For instance when it is foggy, passengers can navigate their cars into the car park using GPS, and yet very well equipped inbound aircraft are forced rely on 50 year old technology VOR approach aids (or worse) which generally result in dissapointment and unnecessary diversions. Once on the ground, only one aircraft is allowed to move at a time, runways are not protected by stop bars and visibility measurements are still made by a human observer standing on a ladder counting runway lights.
There has to be a better way, but its not just a simple matter of throwing money around. There are a huge number of complex factors which need to be thrown into the pot in order to come up with the best long term solutions.
