In the South Pacific (particularly the Soloman Islands, northeast of Australia)
exists a string of cultures so cut off from the rest of humanity,
that the first appearance of airplanes in the 20th century
spawned the emergence of what is known as Cargo Cults
- groups of indigenous people
who have actually devised a religion
built around the occasional appearance of artificial flying machines
and the people who pilot them, and the various exotic goods they bring to trade.
This is apparently what one can expect when primitive societies
suddenly encounter relatively awesome and previously unheardof technology
- especially involving people, and especially when involving the sky.
Indeed, even in our modern world, there are groups
eager to worship alien beings from above as space brothers.
