The fastest flying object known to mankind is not a rocket or a missile, but a manhole cover, which was accidentally created by the Americans in 1957 due to experiments and has a speed of 206 times the speed of sound
Nuclear powered manhole covers
In 1957, the staff in the United States was planning to conduct an underground nuclear explosion test, in short, the content of this experiment was to dig a deep hole in the ground, similar to a cave, put the planned equivalent of nuclear material into the bottom and detonate, after the end of the nuclear explosion, the relevant personnel can analyze the results of the experiment through the detection device and soil residues placed in the hole, in order to prevent the leakage of material pollution and other unfathomable consequences, the implementation of this plan personnel placed a special manhole cover at the wellhead of the cave. Made of pure steel, more than 10cm thick, according to the calculations before the test, the equivalent of this nuclear explosion is very small, almost will not affect the ground, plus this special manhole cover, should be foolproof.
But the results of the test greatly surprised everyone, the original calculated small nuclear explosion, the final release of energy actually greatly exceeded the calculated value, a large number of high-temperature air flow along the wellhead climbed rapidly, and finally rushed out of the hole at an unimaginable speed, and the manhole cover that was originally firmly embedded in the hole was instantly rushed to the sky at a very high speed.
So what was the speed of this manhole cover at that time? According to the professional speculation after the test, its speed is at least more than 70 kilometers per second, equivalent to 206 times the speed (340 meters per second according to the speed of sound), so it is also jokingly called a nuclear manhole cover by netizens and scientists, so this has an interesting question, what is the result of the final manhole cover? In order to facilitate everyone's guessing, three results are given: 1, it is burned in the earth's atmosphere and 2, due to insufficient power, it falls back to the ground. 3, rushed out of the earth, flew to the universe.
