Just a note. One of my good German friends swears by this website. I think he even knows some of the people who write on it. One of them is also a pilot. So their analyses especially on air craft crashes and mysteries is excellent.
I recall a plane that "crashed" in the Ukraine some years ago and I think these people did a real in depth analysis wherein European experts found actual bullet holes in the plane … as if it had been shot down by a fighter aircraft coming from behind.
Anyhow, this website is excellent: https://dieunbestechlichen.com/
