Do you think there's a 900 Kg manhole cover flying through space at Mac 192 right now?

@SW-User Back in the '50s, the Americans were conducting a bunch of experiments with nuclear bombs. And in one of those experiments, they took a nuclear bomb, shoved it down a vertical shaft in the Nevada Desert, and welded a 900 Kg manhole cover to the top of the shaft. They detonated the bomb, and the manhole cover was blasted away immediately. The camera watching this incident only caught the cover for one frame after the bomb was activated, leading analysts to believe that it was traveling at about 140,000 miles per hour.

It's highly probable that the manhole cover disintegrated before exiting the atmosphere, but if it didn't, then that manhole cover was the first manmade object to enter outer space, and the fastest object mankind has ever launched to date. And if the cover survived the Earth's atmosphere, it's probably still out there, farther out than the Voyager probe.

@BlueVeins Oh yeah, that. I'm pretty sure there would be nothing left of it but plasma if it were accelerated to 230,000 km/h inside the atmosphere.

@SW-User That's the scientific consensus, but hey, you never know. :D
