I had a Rammstein ablum, that if you rewound before track 1 there was a black box audio recording of a plane crash were everyone died. It was pretty macabre. I think the CD cover was like a plane's black box if I remember correctly.
No, that's what they were named after. They released an epinomous song on their first album (Herzeleid) that played with the visual imagery of that disaster ("Rammstein - a human burns / Rammstein - the smell of meat in the air / Rammstein - a child dies / Rammstein - the sun is shining"). They apparently initially wanted to name the band Rammstein Flugschau ("Rammstein flight show") before shortening it to Rammstein. The difference in spelling was accidental but Rammstein is evocative (literally "ramming stone") so it stuck.
The album the parent mentions is Reise, Reise, which is travel themed (in a broad sense of the word), the cover being styled after a black box (being bright orange of course). The flight recording in the pregap literally comes from a black box of a plane crash so that fits.
