At the time this was a shock – how could a stealth aircraft get hit? The F-117 was at the cutting edge of military technology. But it was shot down by an old radar system that used vacuum tubes!
Here is a video with a ~30-minute presentation by the officer who ran the SAM battery. The presentation has English subtitles. The presenter mentions downing an F-16 and also impacting a B-2. The video is a production of Serbia-based TangoSix. A fascinating story.
