Intro UFO in Wild West

Since the last wild west update there were built 3 UFOs around the coco base:
x:11341 y:11399 Crashed on the floor
x:9850 y:11317 Crashed in a mountain
x:10313 y:11023 Flying (this one is the nearest to the coco base)
I want to know why they they are there or why the builders of the server have built it.
I just have three supposions about them:
1:They built them for decoration and in reference of the film "Aliens vs Cowboys"
2:They will do a update about aliens with new guns and new mobs ,and make like a war with them like in the film i named before.
3:They will do a special space to kill aliens and get money like indians camps (but not with special guns ,just to get money) and the "aliens camps" will give u more money than in indians ones but will be harder to kill rush them.
