Please sign your posts with ~~~~! I Had it crash while I was at Sanctuary, Garvey made a comment 'what the hell' and then 'worth checking out?'. So I think to it`s a random place but who knows the game is full of surprise. I looked at the sky I never see anything so I went to the place where the UFO suppose to crash there and see a trail of flame in the sky and when I was close I saw the burned trail on the ground that lead me to the UFO. And while I was near Corvega Assembly Plant I heard a big sound like crash. The preceding comment by Special:Contribs/124.171.63.85 01:05, November 22, 2015‎ I decided to do some exploring without fast traveling.

I've only ever noticed it immediately after quick traveling though. I don't think distance or even a clear view in the direction of the crash matters. The preceding comment by User:Stretch27, 04:53, November 21, 2015‎ Nope, but had it at the starlight drive in. If anyone else can verify that they've seen the ship at Red Rocket that'd be great. My theory is that this is a random encounter that can take place at any locations close enough to the ship's crash site.

So I had the alien ship crashed while I was at the Red Rocket Truck Stop, I almost didn't notice but Danse made a comment and I saw the tell tale smoke streak across the sky.
