You know, I heard a story I could never track down. Apparently the Soviets were working on a rocket that would explode several miles from the ground, which they believed would cause maximum damage. I had heard that all development stopped because the entire team watched on its initial test. They had carefully built an altimeter into the device that triggered the explosion at the desired height. Like all good plans gone awry they completely forgot that a rocket must first go up before it can go down and at launch it hit it's desired altitude on the way up at which point it exploded and took out the entire rocket development team. Anyone know if this is a real thing?
