I remember finding a link to this story on here months ago and loved it but I can't seem to find it again.
It was a relatively short story from what I remember and was available online.
The story was told in the perspective of a rocket scientist at a convention telling a story to a journalist.
The story revolved around him and the CIA coming up with the most dangerous design for a rocket imaginable and intentionally leaking it to the soviet union in the hopes that they would waste money, kill scientists in accidents and just slow down their space program in general
The rocket used a special chemical that I think was called "red hydrogen" that could only be made in a nuclear reactor and was so unstable it only lasted a hour or so.
I think the soviets ended up somehow building the rocket in the end and used the Chernobyl reactor for the red hydrogen. But the rocket failed, crashed and resulted in the Chernobyl exclusion zone.
