Sorry to be a broken record ...
- No new major airport will be built in the UK mainland within the forseeable future
- No airport will be significantly expanded with a second or third runway in the UK mainland within the forseeable future
- Call it 25 years because there is no money or political will to overcome the protesters that now range across many different areas: NIMBY + Green + £££
- The opportunity window closed during the period of 1989~1999
