Cover art for Cosmonaut lyrics by At the Drive-In

I've always felt this was about the Lost Cosmonauts conspiracy theory - i.e. the claim that the Soviet Union had several human space missions fail and the cosmonauts die, but covered it all up.

The lyrical imagery of censorship, crashing and 'dying alone', plus the title of the song, would all fit in.
