I remember this ... and there was a video taken shortly after the crash with a Pole commenting over the eerie (morning?) scene and several gunshots were heard on the video .... the commentater indicating WTF ?
Yes, I’ve seen the video you mention. You hear laughter in the video and gunshots, which the speaker then freaks out about and begins to back away. Some say maybe it was ammunition cooking off in the fire. Don’t know about that.
