Question: Identify the phenomenon
Anyway, here comes the answer:
The phenomenon goes by the name Cargo cult in Melenesia(The clue was Skull Island).
After the Europeans discoveredsic Melenesia and the natives came into contact with European technology, they believed that the fancy goods manufactured by the eurpoeans were created by the ancestral people of the melenesians and that white people have unfairly gained control of these objects.
They also believed that what the white people did with these "cargoes" was a ritual, and that if they do the same rituals, their ancestors will recognise their own people and return the cargoes to their rightful owners, being the melenesians.
In most cases, the melenesians did not know/understand what the technology was, but just imitated what the europeans did. Photo #1 shows a group of melenesian tribals building an aircraft made of hay, and waiting for their ancestors.
Photo #2 shows a group carrying wooden thingies in the shape of rifles, seeing the europeans
Photos #2 and #3 shows "USA" tatoos on the chests of these people without understanding what it meant. They'd seen dead white soldiers with these engravings, thought it was a ritual and did the same to themselves.
A plane made of hay
People marching with wooden rifle-shaped thigies
Clue: The ethnicity of the people and the fake thingies are the biggest clues... Think - Skull Island
