No really, it isn't.
They knew they were there, but they have not had contact with anyone. They were not 'lost', but they are living in the stone age. There is a deliberate policy of non-interference and no contact it seems.
http://www.news.com.au/heraldsun/story/0,21985,23914571-663,00.htmlMr Meirelles, 61, said the "chance encounter" that produced the famous photographs was no accident.
"When we think we might have found an isolated tribe, a sertanista (tribe expert) like me walks in the forest for two or three years to gather evidence and we mark it in our (global positioning system," he told al-Jazeera.
"We then map the territory the Indians occupy and we draw that protected territory without making contact with them. And finally we set up a small outpost where we can monitor their protection."
In this case Mr Meirelles appears, controversially, to have gone out to seek and find the uncontacted tribe in an area where it was known to be living.
"When the women hear the plane above, they run into the forest, thinking it's a big bird," he said.
"This is such a remote area, planes don't fly over it."
What he was looking for was not only proof of life, but firm evidence that the tribes in this area were flourishing – proof in his view that the policy of no contact and protection was working
So it was something of a publicity stunt, and poor research practice perhaps, but these were not poor people living in huts in the jungle. These are people who don't know what an aeroplane is.
