Apparently... in WW2, when different armies took over Pacific Islands the natives saw them bring in lots of goods and cargo. They benefitted from this a tiny bit.
When the war was also the cargo stopped coming, and many decided they could do the same thing the foreigners had done and they would get the cargo like the foreigners.
There were instances where natives would clear airfields and build bamboo control towers, complete with bamboo antenna's and they would even wear 'headphones' while they call in the cargo.
This went on for decades apparently, cults actually sprang up with the natives trying to will in the cargo from the skies just like the foreigners who occupied the islands in the war.
Kind of like UFO enthusiasts.
