You need to look for Kate in the location of the Combat Zone, and you can watch the video on YouTube where you can find the plate.

Keith the location is called the "battle zone" It seems that to find a UFO you need to turn on the antennas as in Fallout 3 it will appear.

There is a card!
Spoiler 
It is where there is a strong bend in the river bed, where the loop is curved upwards. I drew right there on my knee, so don't blame me. Been there a long time ago.

1. Already answered above - location "Combat zone"
2. In order for the UFO to fall / spawn, you need to have a character with level 20 or higher. Look a little to the right of Oberland Station (sort of like that).
And if you look for a bummer
Spoiler 
and yes, I'm a paint master of lvl 100 :)

I once went there on Low Level, there are raiders! Is it stupid to go there again or is the quest given?

When apnesh 20 walk on the map - something should sweep across the sky, leaving a plume of smoke. After that, go to the indicated location.
There will be no quest.
