trashnnav: I dont know where 140000 extra flights are coming from, you need to ask Sir H who states in his report that the 3rd rwy will enable the airport to handle 740000 movements per year which give-or-take a few is 280000 more than now. teevees point ( I think) is that adding another rwy while increasing the no. of movs simply maintains the present level of congestion. actually it must increase it since the airspace doesnt increase to accomodate more flights.
