"More recent events strongly buttresses that this decision to cut off hopes of contact is just fine with the Sentinelese. In 2006, a pair of fishermen were plying their trade, illegally, off North Sentinel Island's shore. Sentinelese archers killed the fishermen. When a helicopter came to recover the bodies, the helicopter too was met with a hail of arrows, and retreated before fulfilling its mission.
What do we know about the Sentinelese? Understandibly, very little. They live in huts and are hunter-gatherers, employing the use of javelins, bows and arrows, and harpoons. They speak a language unique to them (also called, by outsiders, "Sentinelese") which we have no way of translating. The Sentinelese appear to use pig skulls as ornaments of some sort, and have employed the use of red dye in both clothing and what is best guessed to be decoration.
And that, unfortunately, is all we may ever learn. As India has given up almost all hope of making further contact with the Sentinelese, these people are considered autonomous and, in a very real sense, the most isolated people on the planet. It seems like a matter of time before they and their culture die off, becoming a historical footnote. On the other hand, the Sentinelese are resilient -- some estimate that they have lived on North Sentinel Island for 60,000 years, and in any event, the Sentinelese somehow survived the Indian Ocean tsunami of 2004 (which probably hit the island).
