An interesting article has been published in International Airport Review regarding new hub airports, and it lends special attention to Manston Airport. Definitely worth a read.
While this airport struggled to attract passenger services when open, it was very popular with freight airlines, having a 9,000 ft runway and not much infrastructure around the area to cause inconvenience to. Also, Manston played a heroic role during the Battle of Britain in 1940 making it a site worth preserving for posterity. Given its lack of development the airport provided an open canvas for the creation of a new airport fully meeting its users expectations, and with a main railway line passing close to the eastern end of the runway, building a station and providing fast service to St Pancras in a little over an hour was a ‘no brainer.’ Tellingly, this project could have been brought to fruition for a fraction of the cost of the third runway at Heathrow, but sadly, Manston was not even considered by the Airports Commission as a possible option.
