So why did you introduce suspect data claiming it to be fact and the basis for your "THIRTEEN TIMES claim?
What are you on about? The Sheffield research deserves as much respect as any of the data you have presented. Unless you can discredit it. Which you have not done so far.
To summarise your argument
You have not summarised my argument. You have concocted a twisted parody of it which suits your personal agenda. My actual argument is there for all to read in my own earlier postings on this topic.
LHR is the UK's most valuable port for trade
LHR's current status is not the issue here. The debate surrounds the stratospheric cost of providing expansion from this point forward versus the ROI which will result. There is a very substantial opportunity cost associated with allocating public funds to supporting this project as opposed to alternatives. Opposition is justified.
You want this debate to be straightforward. Unfortunately, it isn't.
