UNSC In Amber Clad

I don't know where else to make discussion about this, but after reaching the snowy part, I believe between Sacred Icon and Quarantine Zone levels, I looked up in the sky, and I could see a ship that blows up, and then streaks down to the ground. I don't think it's In Amber Clad, but if I squint hard enough it may could be. Any ideas?

If you're talking about a structure that gets shot down over the library, I believe that is a Sentinel Production Facility.
