What is the state of Christianity among the Huaorani people today?

In January of 1956, several American missionaries (Jim Elliot and Nate Saint being the best known) attempted to reach a remote tribe in Ecuador in an endeavor that has become known as [Operation Auca](https://en.wikipedia.org/wiki/Operation_Auca) . The people group, called [*Huaorani*](https://en.wikipedia.org/wiki/Huaorani_people) , *Waodani*, or (pejoratively) *Auca*, were known for being extremely violent, and when the missionaries met several of them on the beach, the missionaries were killed. Their deaths sparked significant interest in missions, and also ultimately led to many Huaorani people being converted through the efforts of Elisabeth Elliot (Jim's wife) and Rachel Saint (Nate's sister), among others. Now, 60 years later, what is the state of Christianity among the Huaorani? What percentage of the people call themselves Christians? Is there a generational gap? Are there among them any established and/or growing churches, particularly with indigenous leadership?
