Hypothetical. A very large and severely damaged alien ship enters Earth's atmosphere and enters a slow, controlled but decaying orbit and is estimated to crash somewhere in Eastern Europe (omg not America?! ) like Transylvania. The technology on board could boost our technology centuries ahead, not to mention be an edge for whoever secures it, against the opponents.
It's clearly seen by everyone the globe, the news talk about it 24/7, etc etc etc. Mass hysteria, etc.
Would the global powers mount a fast offensive to secure the site ahead of the others? I mean I can imagine Russia rushing everything its got to secure it ahead of NATO, and NATO doing the same. Would there be a conflict over it considering the stakes are pretty high?
Would Russia and China not do anything like that but demand equal rights to investigate the crash? Would they be accepted?
