Apparently all those who favour Silver Fantasy Island assume that "Heathrow will close". In reality, how would this be made to happen?
That question might be better asked the other way round:
"Under what circumstances would UK Plc allow Spanish-owned BAA/Ferrovial to hold it to ransom having decided [for the sake of argument] that a Thames Estuary airport was the future?".
Clearly, whatever happens, it's going to be a great time to be a lawyer ...
