The Scottish airports saga

As with anything involving Edinburgh and Glasgow, the question of which city will get any new airport development is generating more heat than light. This posting from the Edinburgh airport newsgroup is a good summation of the pro-Edinburgh case. Both airports lie to the west of their respective cities. As the writer says, Glasgow airport is on the wrong side of the city to properly serve central Scotland as a whole. Edinburgh is close to main motorway and rail links which can easily be upgraded to serve a larger airport. It is not necessary for a country's airport to be sited at its largest city. After the war, Frankfurt became Germany's main airport despite being smaller than Munich or Hamburg. It is however much more centrally located than the two larger rivals. A message here for Scotland, perhaps?
