UFO in the SKY !!!

We were sailing with an open galleon crew the other day, I was running to the front of the ship when I saw a couple of "lights" in sky that I had never seen before. I pulled out my scope and thought wow, I want a ship like that!! It really looked like a space-ship way up in the sky and I thought what the heck is this? Then it started getting larger, and then I could tell it was actually falling. Then it came into better focus as it was closer to us, but still way up in the sky, and it was a SKELLYSHIP!! When it finally hit the ocean surface, it was in the middle of a Kraken attack!! I've never encountered a Skelly Ship spawn like that, anyone else?
