i wonder where that fastest ever manhole is now
for the unaware, the fastest man-made object ever is a manhole that was blasted off it's drain by a nuclear explosion and was very briefly recorded as travelling at over six times the escape velocity of earth.
i say briefly because even using the slow motion cameras they had for analysis of the blast the manhole was only visible for a single frame in mid air

@PsyChuan that story is amazing! if I'm reading https://www.cnet.com/home/energy-and-utilities/nasa-solar-probe-becomes-fastest-object-ever-built-as-it-touches-the-sun/ right, those jerks at NASA have recently spoiled this great trivia answer. Parker is travelling at about 13 escape velocities
@ryan @PsyChuan the manhole cover is still the fastest object on earth.
