Forget the Falcon 9. The fastest man-made object in history wasn’t a rocket... it was a rusty mistake. ☢️💿 In the summer of 1957, during the height of the Cold War, the US military was conducting “Operation Plumbbob” in the Nevada desert. The goal? Test the containment of underground nuclear explosions. For the “Pascal-B” test, Dr. Robert Brownlee buried a nuclear device at the bottom of a 500-foot concrete shaft. To keep the radiation in, they welded a massive 2,000-pound (900kg) solid steel a

Operation Plumbbob’s “Manhole Test” (officially known as Pascal-B) was a U.S. nuclear test conducted in 1957 at the Nevada Test Site. It involved detonating a small nuclear device in a deep underground shaft capped with a steel manhole cover. The goal was to study high-energy explosive effects and containment methods. | The Galactic Void

The incident was part of Operation Plumbbob, a series of nuclear tests in 1957. Scientist Dr. Robert Brownlee later analyzed high-speed camera footage, calculating the plate's insane velocity. Whether it actually achieved orbit is debated; many physicists believe it would have vaporized from atmospheric friction. The U.S. government never confirmed its fate, and the plate was never tracked or recovered, leaving its final destination one of history's intriguing scientific mysteries. Its speculate
