On 4th April 1972, Thames TV broadcast firsthand accounts of the evacuation of St Kilda that took place on 29 August 1930.
The 36 inhabitants were struggling with hunger and poverty, so with an absence of any help, moving to the mainland became the only option.
The doctor was worried. On an island without cars, no one had learned how to step out of the way of approaching vehicles. More realistically, would their immune systems cope living in a new environment and population?
One family of 8 later lost 5 members to TB, and one man lost his lung to it.
