The British Balloon and Airship Club is the national organisation representing British balloonists.
In order to help maintain good relations with the farmers and landowners on whose property balloonists may land, the BBAC maintains a database of areas to be avoided. These are termed Sensitive Areas and usually relate to things such as intensive livestock areas, etc.
