UFO crash site

The crashed UFO is an unmarked location in the Commonwealth in Fallout 4 just to the east of Oberland station. However, there won't be anything there until the UFO crash occurs.

The crash happens randomly for everyone, and with no obvious triggers. With enough exploring, it will eventually happen, and may be visible with a UFO seen falling from the sky.

Layout
The site features a half-buried UFO in a hillside with a skid area of destruction including broken trees, flattened ground, and scattered flames. The trees all around will be permanently on fire, making the location easier to spot from afar. There isn't anything particularly interesting about the crash site itself (no way to enter the UFO, nor anything to scavenge at the crash) but there is a blood trail of greenish blood leading off to the North. Following this trail, you get to an unmarked cave.

Inside the cave is an alien with an alien blaster pistol and 400-500 alien blaster rounds. The alien will be hostile. It sits near a skeleton and a Ham radio, which is broadcasting in something that resembles an alien language.

Appearances
The crashed UFO appears only in Fallout 4.
