4. A Method to the Madness
Stopping the Earth’s rotation sounds crazy – and it was. However, there was actually a method to the madness and a kernel of logic involved. To launch an ICBM and get its warhead to accurately nuke a target thousands of miles away involves intricate calculations, not least among them planetary rotation. If one could tinker with Earth’s rotation, one could screw up those intricate calculations, and cause ballistic missiles to miss their targets. Thus was born PROJECT RETRO, an early 1960s research effort into what it would take to pause the planet’s spinning.
The project was worthy of Wile E. Coyote in that, like many of his schemes, the science actually works in theory. Once launched, the Cold War’s early ballistic missiles could not be redirected. Because of Earth’s rotation, to hit something with a ballistic missile is like shooting an arrow at a mobile target. In both cases, the shooter has to aim not at where the target is, but at where the target will be in the time it takes the missile or arrow to get there. PROJECT RETRO hoped to ensure that the ICBMs’ targets would not be there when their warheads detonated.
