Instead of restricting night flights more, why not do the opposite!
Make LHR 24/7 airport like any other leading major hubs, DXB for example.
That's who we're aiming to compete against as a great 'hub' aren't we.
And as for the noise/environmental concerns, well... you're happy to intensify them with R3 but to spread them out into a 24 hour operation that's a big no no? Strange logic!
Why can't we maximise what we have now. In reality you have 2 under-utilised runways at LHR! In this 24/7 globalised world of which aviation and so called 'hubs' are crucial, I think the immediate concern should be the incredibly restrictive operating hours not the actual infrastructure currently present.
