The plan is contingent upon an extended T5D already outfitted but maybe they do think that is far enough for a person to walk?
Thanks, you've now filled up my day reading that to see if there's anything else interesting I can learn.
I would have expected the tunnel to at least reach T5D as although I doubt many would walk from A to D there needs to be a way to get there should the TTS fail.
I would have read this as the tunnel would not been built from T5D to T3 presumably they'd just use buses if the link between these two terminals broke down, but I doubt they'd want to use buses between T5C and D which are officially the same terminal.
Is HAL still considering extending to T3 as the ultimate plan is to demolish it (after T2 is extended)?
EDIT: looking at the image attached to this proposal is interesting as it shows the TTS also integrated with T6 (this is the old Labour approved 3rd runway plan, the terminal layout under the new plan, if approved, is different) and T4 as well as T3 and T2.
