The R33 class of British rigid airships were built for the Royal Naval Air Service during World War I but were not completed until after the end of hostilities as part of the Royal Air Force. The lead ship R33 went on to serve successfully for ten years and survived one of the most alarming and heroic incidents in airship history when she was ripped from her mast in a gale. She was nicknamed the Pulham Pig by locals and is immortalised in the village sign for Pulham St Mary.
