An unbelievable able story
As two UH-60L was hovering above the Amazon, they saw a field of grass that has little spots. One of the pilots looked down with his telescope and saw that it was something weird. They reported to control tower and they got permission to decrease their height. When they saw that it was walking sticks. The stick started throwing sticks at the helicopters and one of the stick hit a helicopter. The pilot was so freaked out that they flew straight to the airport without asking for permission. After that, lots of people wanted to find the walking sticks but no one found it.
