Good Day All,
On the 21st of April 2007, the Great Britain division will be proud to present London Traffic, an event where the whole of the London TMA will be online from 1700z until 2200z. You can fly to and from London's Major airports:
Heathrow, Gatwick, Luton, Stansted and London City. Expect full aerodrome control as well as over 6 area controllers for the congested London Skies!
