Have we reached saturation point ?
There is more talk around regarding a fourth London airport. But is it a feasible option wrt ATC capacity ?

Say for example, you had an open chequebook, would the technology support it ? Not talking about bodies at screens, - that's another issue well covered here. I am talking about the actual hardware, systems and general infrastructure.
