No, you only have one. It doesn't matter where you got it. You could've stolen it from the aliens, grabbed it off ebay (yes, Ai-chan assure you, they sold flying saucers on ebay) or maybe you built it yourself. Nobody else have this. The flying saucers are like popular culture flying saucers. They can float and fly without any sound, they're faster than jet planes and can't be detected by radar. They also have pretty lights. How would you troll people of Earth with it? As for Ai-chan, Ai-chan would drop beer or pizza on a random fishing boat on a random night and wait for the headlines the next day, "Aliens dropped beer in the middle of the sea."
