Rochester Airport, a grass runway airport located in North Kent.
This Airport is home to Kent, Surrey, Sussex's Air Ambulance secondary base as well as a few flying schools and clubs. Rochester is different as it is a major stopping location for fuel, for helicopters of all types including military, NPAS and of course private. The Airport is located under the London TMA meaning above is a major sector of Airspace of planes climbing out of London Airports and descending on there approaches.
To get to this spot at Rochester you have to cross the taxiway which is highly different to any other airport that I have visited on the channel.
