Hi,

I just remember having read an article in the cqDL, the German ham radio
magazine, a few months back. In this article a radio ham reported that he
was a passenger in a small plane that had to do an emergency landing
somewhere in the middle of the jungle in Brazil, in the 50ties or early
60ties. The radio equipment on board the plain was destroyed but the guy
remembered his own experiments with spark transmitters a few years back and
so he used some parts of the plane's engine and the wrecked radio to build a
very simple spark transmitter, powered by the plane's batteries. With his
SOS call he was then able to raise the attention of a couple of stations and
they were all rescued.
