Ok, sure! From what I can remember of it ...
Jim Elliott, Nate Saint, and 3 others (forget the names) were missionaries in Ecuador in the 1950s. Nate was a pilot with Mission Aviation Fellowship, and the group had a loose connection to HCJB World Radio (which I am joining now). They were based in a town called Shell, just into the jungle on the eastern slopes of the Andes. (I still haven't figured out why there is a town called Shell in a Spanish speaking country.

Not a Spanish name at all!)
There was this group of unreached savages called the Aucas who lived deep in the jungle. No other group of outsiders had ever successfully contacted them -- if they got too close, the Aucas simply killed them!
These five missionaries were determined to win these people for Christ. They flew out in a small plane over the Auca tribe and lowered gifts in baskets down to the Aucas. The savages also put things into the baskets to return to the missionaries. I think they also talked through some type of radio system. This continued for quite some time (several months I think).
Finally, the missionaries decided they had built up enough trust from the Aucas that they could land and visit them in person. One morning they landed the plane on a sandy riverbank near the settlement. The Aucas came ... and promptly murdered all of them!
Later, the widows of the missionaries went back to the tribe. The Aucas accepted the widows and eventually they came to know Christ! Some of the very men that killed the missionaries have toured the States speaking of how God had changed their lives.
The name of the tribe was changed from Auca ("savage") to Waoroni (hmm, I forget the meaning now... "people" maybe?)
That story has motivated a LOT of young people to get into missions. It also had a fairly large impact on me. There is a book written by Elisabeth Elliott, Jim's widow, that tells the whole story. I want to read it someday, haven't yet. It's called
Through Gates of Splendor.
Like I said, I was in the Mission Aviation Fellowship hangar in Shell and saw some of the history of this mission. It's pretty moving. HCJB World Radio now runs a hospital in Shell where they give medical care to the jungle inhabitants. That hospital was a dream of Nate Saint.
Someday I hope I can actually go to Auca/Waoroni territory. Alas, that kind of thing isn't what I will be there for, so it will probably have to be on vacation time.
