We are a group of people who feel Manston Airport should be used much more than it is at the moment. It should be a major passenger airport, to rank with others in the South East.
Manston Airport already exists in East Kent with one of the longest runways in the country, and its planes take off almost straight over the sea. Road access to Manston has recently been upgraded, and there is now a new dual carriageway running through East Kent, called the A256 which runs north-south, with its exit close to Manston.
Manston also has a railway running nearby. The latest estimate from Network Rail of the cost of building a train station at Manston Airport would be some £10.2m (Report prepared for KCC, January 2011). That's still infinitely less than the estimated cost of £50 thousand million for a brand new airport in the Thames estuary.
But even without a new station at the airport, Ramsgate is only two miles from Manston and a shuttle bus could easily run between the airport and either Ramsgate or Minster stations. Such a shuttle bus already works very effectively at Luton airport.
