Contacting Uncontacted Tribes - eh?

I suppose it's good to know that there are still tribes out there that "we" haven't made contact with but then we just have - by flying around over the top of them. Survival International has been doing a lot of work with hard to reach groups and Human Planet film on telly last night showed some footage. I found this compulsive and repulsive at the same time. http://www.uncontactedtribes.org/brazilfootage Anyway make your own mind up. I always remember an early book by some explorer in the 60's that notes a tribe "worshipping" a sliver bird and smoke tail that passed high over their village, same time, same direction.
