Epsilon: Well, your yards must be different from mine, but I sat for quite a few years in T2 office block and for most mortals used to the distances at many of the worlds airports it is very close to T3,- and even more so now with the building of T3s A380 stands.
Moving on from that, the listing of T2 and Queens would be a nonsense and would severely limit future passenger growth in the CTA. Airport design and passenger expectation have moved on a lot since the 1950s when T2 was originally designed. The BAA have done well in modifying the terminal but it it now needs to go. An airport is dynamic and must move on,- the Viscounts, Caravelles and Comets have gone and so must the building. If LHR does not keep pace with the world the customers simply go elsewhere,- Amsterdam, Paris to mention just 2.
It is good to see the BAA/HAL coming up with new vision,- long may it continue.
