I believe that EGSS needs a second runway, slot 1 departures are a nightmare on 23 even more so on 05, however there needs to be better rail links, STN Express is unreliable and services are often canx, after 0030 that's it until the morning.
I do feel that there are a lot of smoke screens going up with the application for "several" runways at EGSS when in fact they eventually propose to build only one the locals and the "do gooders" feel that they have won the battle.
