Just reported on Sky.
Apparently there is a train of thought that Heathrow has really shot itself in the foot big style re 3rd runway with the "no compromise from shareholders re Heathrow Hub".
Has gone down like a proverbial lead balloon !
Maybe it's because the Heathrow Hub option requires "mixed mode" operations at all time with no "segregated mode" and no alternation, otherwise the number of movements cannot be increased sufficiently to have a return on investment, in which case there's no point.
If this scheme was implemented, there would be "
a train of thought that Heathrow has really shot itself in the foot big style" re. the residents who live under the flightpaths.
