The operation consisted of 29 explosions, of which only two did not produce any nuclear yield.Twenty-one laboratories and government agencies were involved. While most Operation Plumbbob tests contributed to the development of warheads for intercontinental and intermediate range missiles, they also tested air defense and anti-submarine warheads with smaller yields.
Although likely never achieving orbit due to aerodynamic drag, the first macroscopic object to obtain Earth orbital velocity was a "900kg manhole cover" propelled by the somewhat focused detonation of test shot Pascal-B in August 1957. The use of a subterranean shaft and nuclear device to propel an object to escape velocity has since been ...

In a video taken at the scene, spectators can be heard saying, "I've never heard an explosion like that before." Another can be heard estimating the manhole cover jumped "40 or 50 feet."
A round manhole and its cover. A manhole cover is a removable plate forming the lid over the opening of a manhole, an opening large enough for a person to pass through that is used as an access point for an underground vault or pipe. It is designed to prevent anyone or anything from falling in, and to keep out unauthorized persons and material.

Beside material launched by humans into space with a range of launch systems, some instances particularly nuclear produce artificial ejecta, like in the case of the Pascal-B test which might have ejected an object with a speed of Earth's escape velocity into space. [13] [14]
A bright green liquid leaked from a New York City manhole cover in bizarre footage. There's literal green sludge bubbling up from the ground next to World Trade Center right now,” Dan Pantelo ...
