" The Heathrow Hub proposal could be a template for a 4th parallel rwy "
That's the problem with LHR cheer -leaders - they don't know when to stop....
Frank, you've just handed more ammunition to the Anti's...........................
Harry, read the entire post. The entire paragraph that you selectively quoted from reads as follows:
"Sometime in the future, once aircraft are even cleaner and quieter than now and mixed/segregated mode operations are no longer an issue, and once the technical and safety concerns are sorted, the Heathrow Hub proposal could be a template for a 4th parallel rwy."
Please note the words "cleaner and quieter" and "mixed/segregated mode operations are no longer an issue".
The last line reads as follows:
"However, it's academic for all of us, we'll all be long dead."
Don't think that this is giving anyone any ammunition.
The people you mention don't need any help from me. They have 10 people who have made half of all the complaints about aircraft noise.
Half of Heathrow Airport's 25,000 noise complaints for the last three months of 2016 were made by 10 people | City A.M.
