I still don't understand how building an airport can be so difficult, and how we've apparently gotten worse at it over time. There's a weird mix of ego and incompetence at work in the BER project (e.g. smoke vents installed in the floor for artistic reasons, despite the face that smoke rises). Yet at its core, an MVP of an airport would be a runway with a building next to it + fuel and security services. It baffles the mind that this can be such a shitstorm. I can only perceive this to be bikeshedding at a national scale.
