Hello, can you tell me about Tristan da Cunha? 
 Sure. Tristan da Cunha is a group of remote volcanic islands in the south Atlantic Ocean and also the main island of that group. It is part of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha. 
 What's popular in culture? 
 In popular culture, Tristan da Cunha's longtime Police And conservation officer, Robert A Heinlen's memoir Tramp Royale, written by Conrad Glass, devoted a chapter to his near visit to the island. 
 What additional information can you tell me? 
 The island has a permanent population of 275. 
 Oh wow, how is their economy? 
 Fishing boats from South Africa service the islands eight or nine times per year. 
 Interesting, what else can you tell me about that? 
 There is no airstrip of any kind on the main island. So this means, the only way to travel in and out of Tristan is by boat. 
 Cool, what else? 
 The island is named after Portuguese explorer Tristan Da Cunha. 
 Thank you so much for your help! You've been great! 
 You're welcome.
