I'm not an expert on Lydd so I hope someone else more familiar with Lydd will be able to help answer 2 questions
Why exactly does Lydd need a runway extension, and who are likely to be the new additional users of the airport ?
Additionally, how does this strategy take into account developments in the last few years at London-City, Manston, Gatwick, Shoreham and the HS1 train line ?
I'm not saying it shouldn't happen - just want to understand the business case and try to see if it makes sense (preferably without having to put on rose tinted fanboy glasses !)
