See Hear - Series 29 - Episode 37

Radha Manjeshwar takes a day-trip to Cardiff to check out some new technology aimed at improving access for deaf visitors to Cardiff Castle. We take to the skies with one of the UK's few deaf pilots to find out about the obstacles he overcame in order to pursue his childhood dream. We also continue our journey tracing the development of British Sign Language, picking up the story just as sign language has been banned from the classroom.
