From the BBC article "nearly 800 homes would have to be demolished to build the new runway."
He was complaining that nimbyism prevents/delays developments like this. I was pointing out, possibly badly, that it's easy to complain about the delays etc when it's not you having your home destroyed. Let's remember that these people will be FORCED to sell their homes and will be out of pocket as the homes will be brought at market rate with a little compensation on top - it takes no account that the people forced to move will then be forced to pay stamp duty, moving costs and see their hardwork on their homes and gardens destroyed.
I'm certain costs will be covered in any compulsory purchase order.
As an aside, your concerns seem to be the exact definition of a NIMBY. Personally, I prefer progress and would be happy to take a supposed hit for the greater good.
