well fire cover could be arranged by the RAF airfield Appliences and domestic ones (for the terminal responsabilities as i know LHR and LGW have one) as there are just as good as the Civil ones! – security – hmmm tho!
http://www.vatsim.net is the site- VATSIM is the world largest online flightsim community which at peak times can offer over 600 pilots/atc and staff online at once – the uk is one of the busier areas along with the US – At present i am flying EGNM-GCTS and there are 314 online – usually a bit lower in the daytime – theres a page that allows you to apply for an ID – it’s usually no problem to apply
Its the way they are hubbed – LBA only has a 3x daily FR Dublin link – no other loco – and a catchment are of 7 million within an hour of something – it’s something which it has been gagging for!!!
