Imagine, if you will, an alien ship that is gathering species from multiple planets to put them into some kind of zoo. After some time collecting, it sets a course for its homeworld. However, due to mechanical error, it comes out of hyperspace above Earth and crash lands here. The ship itself is automated, however, it is carrying thousands of species of alien creature. The ship, though it has crashed, is still working to keep the animal cargo alive. How would the world react? I want to get a few perspectives here; scientific, military, governmental, etc.
