Skylion; your profile states that you are an aviation consultant. I doubt whether terminal buildings will feature on your portfolio
You assert that T2 and T3 are within yards of each other. I can assure you they are not .
T 5 and T 3 should always have been designed as just 2 entrances to one terminal
What on earth does that mean and how can they be??
As for airside walkways between T2 and T3 you must be crazy. Who'd want to walk that far? You may as well advocate walkways between T2 and the West end!!
Underground concourses what nonsense, this is England not the Australian desert.
Give the two fine buildings a facelift as they did with T3 and dont bother thinking about underground potential either, the place has more tunnels than a German POW camp.
